1) Set one equation equal to one variable, typically solving for x or y.
2) Substitute the expression from step 1 into the other equation.
3) Solve the resulting equation from step 2 for the remaining variable.
4) Substitute the value of the remaining variable into the expression from step 1 to find the value of the other variable.
5) Write the solution as an ordered pair (x, y).
