Question

Graph the following system of equations and find the x-coordinate of the solution

4x + 4y = 44
y = 2x + 2

Answer 1

In order to find the x-coordinate from both equations, we can isolate the y variable on the left-hand side of both equations, and then set them equal to one another, and solve for x (second equation is already done for us):

4x + 4y = 44

4y = 44 - 4x

y = -x + 11

2x + 2 = -x + 11

3x = 9

x = 3
