What's the answer to 4 (3+c) + c=c+4

4 (3+c) + c=c+4

mutiply the bracket by 4

(4) (3) = 12

(4) (c) = 4c

12+4c+c = c+4

12+5c = c+4

Move c to the other side

Sign changes from + c to - c

12+5c-c = c-c+4

12+5c-c=4

12+4c = 4

Move + 12 other side

Sign changes from + 12 to - 12

12-12+4c = 4-12

4c = - 8

divide by 4 for both sides

4c/4 = - 8/4

c = - 2

Answer: c = - 2
