1) x = 2y + 11
2) Substitute the value of x from step 1 into the first equation: -7(2y + 11) - 2y = -13
3) Simplify and solve for y: -14y - 77 - 2y = -13
4) Simplify further: -16y - 77 = -13
5) Solve for y: -16y = 64
6) Simplify: y = -4
7) Substitute the value of y into the second equation: x - 2(-4) = 11
8) Simplify and solve for x: x + 8 = 11
9) Solve for x: x = 3
10) The solution to the system of equations 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 (10 points)
y = -4
x = 3
(3,-4)
x -2y = 11 --> x = 2y + 11
x - 2(-4) = 11
x + 8 = 11
-14y - 77 - 2y = -13
-16y = 64
-16y - 77 =-13
-7(2y + 11) - 2y = -13
