Question

Put the steps in order that are used to solve the following systems of equations by substitution.
-7x-2y=-13
x-2y=11

| x-2y=11-->x=2y+11, -16y=64, x+8=11, -14y-77-2y=-13, -7(2y+11)-2y=-13, x-2(-4)=11, x=3, y=-4, -16y-77=-13, (3,-4)
Use all the following systems

Answer 1

1. Write one of the equations in terms of one variable (in this case, x or y).
2. Substitute the expression for that variable into the other equation.
3. Solve the resulting equation for the remaining variable.
4. Substitute the value of the remaining variable into the expression you found in step 1.
5. Solve for the variable in step 1.
6. Plug the value of the variable from step 5 into one of the original equations to find the value of the other variable.
7. Write the solution as an ordered pair (x, y).
