Y – 11 + 11 = 8 + 11 y + 0 = 19 y = 19 Example: –r + 9 = 13 Subtract 9 from both sides of the equation. –r + 9 – 9 = 13 – 9 Simplify both sides of the equation. –r + 0 = 4 Add 0 to –r. –r = 4 Are you finished? No! The value of the variable must be positive, and r is negative. You need to make the variable positive. You can do that by multiplying both sides of the equation by (–1). (–1)(–r) = 4(–1) r = –4 32 Team-LRN – SOLVING BASIC EQUATIONS – Practice Solve these equations without the use of a calculator.

You can use the variable x to represent the answer to the problem. You want to know how much you can earn this summer.
