Step 2: Graph the equations using the slope and y-intercept or using the x- and y-intercepts. In the second equation y is not multiplied by a constant so it can be isolated in fewer steps. Step 1: Analyze what form each equation of the system is in. The first step would be to choose one of the equations and solve it for either x or y. The coordinates of the intersection will be the solution to the. If the lines intersect, identify the point of intersection. Another method of solving equations is by graphing each equation on a coordinate graph. Determine whether the lines intersect, are parallel, or are the same line. Graph the second equation on the same rectangular coordinate system. It does not matter which equation you choose first, or which variable you solve for first the values for both variables will be the same.įor example, given the system of linear equations: To solve a system of linear equations by graphing. This method works by solving one of the linear equations for one of the variables, then substituting this value for the same variable in the other linear equation and solving for the other variable. To solve a system of linear equations without graphing, you can use the substitution method.
