Answer:

Step-by-step explanation:

1) 6r - 12 + 6r + 11 = 11

Combine like terms

6r + 6r - 12 + 11 = 11

12r - 1 = 11

12r = 11 + 1

12r = 12

r =12/12

r = 1

2) 8m + 5 + 13m - 5 = 42

8m + 13m + 5 - 5 = 42

21m +0 = 42

21m = 42

m = 42/21

m = 2

3) 4x + 5 + 5x + 6 = 29

4x + 5x + 5 + 6 = 29

9x + 11 = 29

9x = 29 - 11

9x = 18

x = 18/9

x = 2
