Put the steps in order that are used to solve the following systems of equations by substitution.
{−7x −2y = −13x − 2y = 11
Arrange responses in the correct order to answer the question.
1. Choose one equation and solve for one variable in terms of the other.
2. Substitute the expression for the variable from step 1 into the other equation.
3. Solve the resulting equation for the remaining variable.
4. Substitute the value found in step 3 back into either equation to solve for the first variable.
5. Write the solution as an ordered pair (x, y).
