1-3 Solving Equations

One-Step EquationsExamples:

1). x + 3 = 15

2) p – 5 = 20

3) 2d = 16

4). = 24

Multi-Step Equations Examples—

5). 2p + 15 = 29

6). 14 – 3n = -10

7). 27 = -9(y+5)

8). 7a – 3a + 2a – a = 16

More Examples 9). 3f – 2 = 4f +5

10). + 5 = 10

11). - 2 = 8.

12). 15 – x = 25

Solving For a Variable Use the SAME properties of equality to

solve an equation or formula for a specific variable.

Examples:13). Solve D = R x T For T.

More Solving for Variables Examples: 14). A = 4*S + P (Solve For S)

15). X = (Solve for a)

Writing an equation from a scenario

ExampleSet up an equation to solve the following

problem:

16). Jon and Morgan arrive at Sunnybrook Lanes with $16.75. Find the maximum number of games they can bowl if they each rent shoes. (Shoes are $1.50 & Each Game costs 2.50)
