This week we learned substitution. To use substitution you have to re arrange one of the equations into y intercept form. You then put the new equation into the X spot in one of the original equations where the Y is and and that’s how you solve for y. When you get your answer put it into the y spot in one of the origin equations and solve for X. You can then verify your answers by putting the X and Y intercepts into the original equations and make sure they are true for both.
