1) x = 2y + 11
2) -7x - 2(-4) = -13
3) -7x + 8 = -13
4) -7x = -21
5) x = 3
6) y = -4
Therefore, the solution is (3, -4)
Put the steps in order that are used to solve the following systems of equations by substitution.
-7x - 2y = -13
x - 2y = 11
1) y= -4
2) -7 (2y + 11) - 2y = -13
3) (3 , -4)
4) -16y = 64
5) x - 2y = 11 x = 2y + 11
6) -16y - 77 = -13
7) -14 - 77 - 2y = -14
8) x = 2 (-4) + 11 x =3
