Testing a solution to a system of equations – Khan Academy
If you are asked if a point is a solution to an equation, we replace the variables with the given values and see if the 2 sides of the equation are equal (so is a solution), or not equal (so not a solution). A solution to a system of equations means the point must work in both equations in the system. So, we test the point in both equations. It …

Solving a system of equations by subtraction is ideal when you see that both equations have one variable with the same coefficient with the same charge. For example, if both equations have the variable positive 2x, you should use the subtraction method to find the value of both variables.

In the next section we will verify that this point is a solution to the system. In the following example, you will be given a system to graph that consists of two parallel lines. Example Graph the system y = 2 x + 1 y = 2 x − 3 using the slopes and y-intercepts of the lines. [reveal-answer q=478796″]Show Solution [/reveal-answer]

1.2: Finding solutions to systems of linear equations
Based on these observations, we take note of three operations that transform a system of linear equations into a new system of equations having the same solution space. Our goal is to create a new system whose solution space is the same as the original system’s and may be easily described.

For each equation, you need to find at least two points. Then you draw a line that goes through the points. The easiest way to find the points is to just pick a value for one of the variables (x or y) and then solve for the other variable. For instance, take the equation y = -2x + 4 Let’s say x = 0 y = -2x + 4 y = -2 (0) + 4 y = 0 + 4 y = 4

5.1: Solve Systems of Equations by Graphing
Solutions of a system of equations are the values of the variables that make all the equations true. A solution of a system of two linear equations is represented by an ordered pair ( x, y ). To determine if an ordered pair is a solution to a system of two equations, we substitute the values of the variables into each equation.

Solutions to Systems of Equations: Explanation, Review, and … – Albert
The solution set to a system of equations will be the coordinates of the ordered pair (s) that satisfy all equations in the system. In other words, those values of x x and y y will make the equations true. Accordingly, when a system of equations is graphed, the solution will be all points of intersection of the graphs.

When you will have to solve a system of linear equations in a later math class, you will usually not be told which method to use. You will need to make that decision yourself. So you’ll want to choose the method that is easiest to do and minimizes your chance of making mistakes.
