Put the steps in order that are used to solve the following systems of equations by substitution. −7x−2y=−13

Question

x−2y = 11 are the equations don't give me steps in words just put the numbers in order give me 10 steps

x - 2y = 11 --> x = 2y + 11
-16y = 64
-16y - 77 = -13
x - 2(-4) = 11
x + 8 = 11
y = -4
x = 3
-14y - 77 -2y = -13
-7 (2y + 11) -2y = -13
(3, -4)

Answer 1

1. Rewrite one of the equations in terms of one variable (x or y).
2. Solve for one variable in terms of the other.
3. Substitute the expression from step 2 into the other equation.
4. Simplify the equation after substitution.
5. Solve for the remaining variable.
6. Substitute the value found in step 5 back into one of the original equations.
7. Simplify the equation after substitution.
8. Solve for the remaining variable.
9. Check the solution by substituting the values back into both original equations.
10. Write the solution as an ordered pair (x, y).
