WebThe method of solving "by substitution" works by solving one of the equations (you choose which one) for one of the variables (you choose which one), and then plugging this back … WebJan 10, 2024 · Substitution Method: This method involves isolating for one variable (x/y) of Line 1 then substituting that variable into Line 2. This will allow you to isolate and solve for the other variable (y/x). Once you have the x- and y- coordinates, you then have the solution which is the point of intersection between the two lines. Line 1: y = 6 ...
