The substitution method answer for the following equations

Question

x = -3y + 6 4y + x = 13

Answer 1

x = -3y + 6

4y + x =13

Plug the top expression for x into the bottom equation.

4y + (-3y + 6) = 13

Solve for y and get

y = 7

Plug this value of y into either equation and solve for x. Using the top equation,

x = -3(7) + 6 = -15
