Solving Systems of Equations: The Substitution Method

Solving Systems of Equations: The Substitution Method. Example 1. Solve using substitution. y = 3x. 2x + 4y = 28. y = 3x. 2x + 4(3x) = 28. y = 3(2). 2x + 12x = 28. y = 6. 14x = 28. x = 2. (2,6). REMEMBER To Check: Always plug solution into original equations . Example 2.
