Answer 1

Answer: #20, x = 3

              #21,  x = 1/2

Step-by-step explanation:

#20) x + 4 + x + 2+ x + 5  = x + 3 +x+3+x+1+x+1

3x + 11 = 4x + 8

-3x           -3x

      11= x + 8

    - 8       - 8

     3   =   x

#21)  12x(5) = 6x + 9 + x + 10 + x + 7

         60x =8x + 26

          -8x    -8x

         52x = 26

 divide both sides by 52

         x = 1/2
