Solve all and: (will give QUICKLEY FOR BEST ANSWERS!! 1. 6r - 12 + 6r + 11 = 11 (what does r equal?) r =
2. 8m + 5 + 13m - 5 = 42 (what does m equal?) m =
3. 4x + 5 + 5x + 6 = 29 (what does x equal?) x =

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

r = 1   m = 2  x = 2

Step-by-step explanation:

1. 6(1)-12+6(1)+11=11

2. 8(2)+5+13(2)-5=42

3. 4(2)+5(2)+6=29
