                                                 85 + c/4  =  99

Subtract 85 from each side:          c/4  =  14

Multiply each side by  4 :                  c  =  56
85+c/4=99

85+1/4c=99

1/4c+85=99

Subtract 85 from both sides.

1/4c+85−85=99−85

1/4c=14

Multiply both sides by 4.

4*(1/4c)=(4)*(14)

c=56
