Put the steps in order that are used to solve the following systems of equations by substitution.
Solve: {−7x − 2y = −13 x − 2y = 11
y = −4
−7(2y + 11) − 2y = −13
(3,−4)
−16y = 64
x − 2y = 11→ x = 2y + 11
−16y − 77 = −13
−14y − 77 − 2y = −13
x = 2(−4) + 11→ x = 3
1. Substitute y = -4 into one of the equations to solve for x
2. Solve for x using the substitution x = 2y + 11
3. Determine the value of x and y in the system of equations, which is (3, -4)
bot put the steps in order
1. Solve for y in one of the equations (y = -4)
2. Substitute y = -4 into the other equation to solve for x (x = 3)
3. Determine the solution of the system of equations: (3, -4)
