1 answer

1. Solve one of the equations for one variable in terms of the other.
2. Substitute the expression found in 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 of the original equations to find the value of the other variable.
5. Write the solution as an ordered pair (x, y).
