Do Now Solve. 1. 6n + 8 – 4n = 20 2. –4w + 16 – 4w = –32 3. 25t – 17 – 13t = 67 4. 12 = 2(x + 7) + 4 n = 6 w = 6 t = 7 x = –3

3
**To solve equations with variables on both sides:**

first collect like terms on the same side then use the inverse operations to solve. Solve. 1. 60 – 4y = 8y 2. 40 – 2y = 6y + 4y + 4y + 2y + 2y 60 = 12y 40 = 8y 12 12 8 8 5 = y 5 = y

4
**To solve equations with variables on both sides:**

first collect like terms on the same side then use the inverse operations to solve. 3. –5b + 72 = –2b 4. –8b + 24 = –5b + 5b + 5b + 8b + 8b 72 = 3b 24 = 3b 3 3 3 3 24 = b 8 = b

5
**To solve equations with variables on both sides:**

first collect like terms on the same side then use the inverse operations to solve. 5. 7c = 2c + 55 – 3m = 4m + 14 – 2c – 2c +3m +3m 5c = 55 49 = 7m + 14 5 5 -14 -14 c = 11 35 = 7m 7 7 5 = m

6
**To solve equations with variables on both sides:**

first collect like terms on the same side then use the inverse operations to solve. 7. 8f = 3f + 65 – 3q = 6q + 9 +3q +3q – 3f – 3f 5f = 65 54 = 9q + 9 5 5 - 9 - 9 f= 13 9q 45 = 9 9 5 = q

7
Practice- Solve. 9. 14n = 11n + 81 10. –14k + 12 = –18k y = –4y – 19 p = 10p + 54
