Clarify math equations

One way to think about math equations is to think of them as a puzzle. Each piece of the equation fits together to create a complete picture. When one piece is missing, it can be difficult to see the whole picture.

## 4.2: Solve Systems of Equations by Substitution

From the second equation you get y = 3.25x + 14 and substitute into first equation. 2.5x – 3 (3.25x + 14) = – 13. 2.5x – 9.75x – 42 = – 13. – 7.25x = 29. x = -29/7.25 = – 4. Now
