Substitution method for solving linear equations:

Step 1: Solve one linear equation in terms of x for y.
Step 2: In the other linear equation, substitute that expression for y. You'll be given an x equation.
Step 3: Once you've solved this, you'll obtain the intersection's x-coordinate.
Step 4: In either equation, enter in x to determine the matching y-coordinate.
