1 2.1 Solving One Step Equations

2 Addition Property of Equality For every real number a, b, and c, if a = b, then a + c = b + c. Example 8 = 5 + 3 For every real number a, b, and c, if a = b, then a + c = b + c. Example 8 = 5 + 3 8 = 5 + 3 8 + 4 = 5 + 3 + 4 8 = 5 + 3 8 + 4 = 5 + 3 + 4 Add 4 to the left you must add 4 to the right

3 Subtraction Property of Equality For every real number a, b, and c, if a = b, then a − c = b − c. Example 8 = 5 + 3 For every real number a, b, and c, if a = b, then a − c = b − c. Example 8 = 5 + 3 8 – 4 = 5 + 3 - 4 Example 8 = 5 + 3 8 – 4 = 5 + 3 - 4 Subtract 4 on the left side you must subtract 4 on the right

4 Problem 1 Add 8 to both sides Isolate variable

5 Problem 4 Add 17 to both sides Isolate variable

6 Problem 10 Subtract 5 from both sides Isolate variable

7 Problem 24 Subtract 29 from both sides Isolate variable

8 Homework Page 77 1-18 Odd
