The document provides examples of solving various math equations by writing an equation for the problem, solving the equation, and checking the solution. The examples include solving equations with variables, integers, and consecutive numbers. Key steps shown are writing the equation, solving for the variable, and checking the work by plugging the solution back into the original equation.

1. Solve. Then check your solution. Check: 5(10) – 13 = 37 50 – 13 = 37 37 = 37  Example 4-2a

2. Solve 4a – 42 + 42 = 14 + 42 4a = 56 4 a = 14 Check: 4(14) – 42 = 14 56 – 42 = 14 14 = 14 Example 4-2b

3. Solve (12) (12) s = –240

4. Solve - 4 - 4 = 33 (11) (11) a = 363 Example 4-3c

5. Solve ( ) (-3) (-3) r = 14 Example 4-4a

6. Write an equation for the problem, then solve the equation. Eight more than five times a number is negative 62. n 8 62 5 5 5 n = –14 Example 4-5a

7. Write an equation for the problem, then solve the equation. Find three consecutive odd integers whose sum is 57. 1st odd number 2nd odd number 3rd odd number + + = 57 n n + 4 n + 2 17, 19, 21 Example 4-6a
