1. 3.1-3.2 Solving One Step Equations subtract 3 Adding or subtracting the same number from each side of an equation produces an equivalent equation. Addition and Subtraction Property of Equality

2. Solving Multiplication & Division Equations Multiplying or dividing each side of an equation by the same number produces an equivalent equation. 3x = 6 x = 2 divide into 3 groups

3. In order to solve One-Step Equations use the inverse operation to isolate the variable. using division 2x = 24 2 2 x = 12 using multiplication x 3 = 4 x 3 3 3 x = 12 using addition x - 2 = 6 x - 2 + 2 = 6 + 2 x = 8 x + 5 = 7 x + 5 - 5 = 7 - 5 x = 2 using subtraction

4. Write and solve an equation to model the statement. Five less than a number n is negative fifteen.

5. Solve the equation. Check your solution. 8.15 + p = 11.39 x - = 1 5 3 5

6. Solve the equation. Check your solution. x -1.5 = -8 -4.8x = 24

7. Simplify and then solve the equation. 4 + d - 7 = 15 0.7w + 2.8 + 0.3w = 3
