Put the steps in order that are used to solve the following systems of equations by substitution.
-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
-14 - 77 - 2y = -14
x = 2 (-4) + 11 x =3
1. Substitute y = -4 into the second equation x - 2y = 11
2. Solve for x by plugging in y = -4 and simplfiying the equation
3. Find the solution (x,y) by plugging in the value of x found in step 2 and the value of y = -4.
put it in order
1. Substitute y = -4 into the second equation x - 2y = 11
2. Solve for x by plugging in y = -4 and simplifying the equation x - 2(-4) = 11
3. Determine x = 3
4. Substitute y = -4 into the equation y= -4 to verify the value of y
5. Confirm the solution as (3, -4)
