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 = 3750 – 13 = 3737 = 37 Example 4-2a

2. Solve4a – 42 + 42 = 14 + 424a = 56 4a = 14Check:4(14) – 42 = 14 56 – 42 = 14 14 = 14Example 4-2b

3. Solve(12)(12)s = –240

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

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

6. Write an equation for the problem, then solve the equation.Eight more than five times a number is negative 62.n8 62555n = –14Example 4-5a

7. Write an equation for the problem, then solve the equation. Find three consecutive odd integers whose sum is 57.1st odd number2nd odd number3rd odd number++= 57nn + 4n + 217, 19, 21Example 4-6a
