Solving Systems by Substitution - DeKalb County School District

Solving Systems by Substitution Solve the system by substitution. Example 1A: Solving a System of Linear Equations by Substitution y = 3x y = x – 2 Step 1 y = 3x y = x – 2 Both equations are solved for y. Step 2 y = x – 2 3x = x – 2 Substitute 3x for y in the second equation. Solve for x. Subtract x from both sides and then divide by 2. ................
