# Write a system of equations that has no solution infinite

Quantum equation predicts universe has no beginning February 9, by Lisa Zyga, Phys. Introduction Sometimes graphing a single linear equation is all it takes to solve a mathematical problem. This is often the case when a problem involves two variables.

Solving these kinds of problems requires working with a system of equationswhich is a set of two or more equations containing the same unknowns. Systems of Equations A system of equations contains two or more linear equations that share two or more unknowns.

To find a solution for a system of equations, we must find a value or range of values that is true for all equations in the system.

The graphs of equations within a system can tell us how many solutions exist for that system. Look at the images below. Each show two lines that make up a system of equations in the graph on the right the two lines are superimposed and look like a single line. How many points in common does each system of lines reveal?

No Solutions Infinite Solutions If the graphs of the equations intersect, then there is one solution that is true for both equations.

## Analyzing the number of solutions to linear equations

If the graphs of the equations do not intersect for example, if they are parallelthen there are no solutions that are true for both equations. If the graphs of the equations are the same, then there are an infinite number of solutions that are true for both equations.

Remember, the graph of a line represents every point that is a possible solution for the equation of that line. So when the graphs of two equations cross, the point of intersection lies on both lines, meaning that it is a possible solution for both equations. When the graphs of two equations never touch, there are no shared points and there are no possible solutions for the system.

When the graphs of two equations lie on top of one another, they share all their points and every one is a possible solution. Graphing as a Solution Method Graphing equations in order to identify a specific point of intersection is usually not a precise way to solve systems because it is often difficult to see exactly where two lines intersect unless you are using a computer-based graphing program that allows you to zoom in on a point.

However, the graph of a system of equations can still give a good idea of what type of solution, if any, exists. How many solutions does this system have? So a system made of two intersecting lines has one solution. How many solutions exist for the system y Plotting both equations, it looks like there is no solution—the lines are parallel.

To check this finding, we can compare the slopes of the equations. Yes, the slope of both lines is 0. They never intersect, so there is no point that lies on both lines, and no solution to the system.

Micaela is trying to find the number of possible solutions for a system of two linear equations. She draws the following graph, which accurately shows parts of the two lines in the system. What can she conclude?

A The system has no solutions. B The system has one solution.

C The system has two solutions. D The system has infinite solutions. Although this view of the graph shows no point of intersection, the two lines do not have the same slope and are slowly converging as x increases, so they will intersect at some point. The correct answer is that the system has one solution. The two lines in the system are converging as x increases and will eventually intersect, meaning that there is one solution for this system.SOLUTION: Please help.

And thanks in advance Write a system of two linear equations that has. a) only one solution,(2,3). b) an infinite number of solutions.

Time. Time is what a clock is used to measure. Information about time tells the durations of events, and when they occur, and which events happen before which others, so time has a very significant role in the universe's organization.

One equation of my system will be x+y=1 Now in order to satisfy (ii) My second equations need to not be a multiple of the first.

If I used 2x+2y=2, it would share, not only (4, -3), but every solution.

Parallel and different y-intercept. (Note that with non-linear equations, there will most likely be more than one intersection; an example of how to get more than one solution via the Graphing Calculator can be found in the Exponents and Radicals in Algebra section.) Solving Systems with Substitution.

There can be zero solutions, 1 solution or infinite solutions--each case is explained in detail below. Note: Although systems of linear equations can have 3 or more equations,we are going to refer to the most common case--a stem with exactly 2 lines.
