Question

-3c-12=-5+c

Answer 1

-3c - c = -5 + 12 (I've bought the c to the left side and -12 to the other side)
-4c = 7
c = -7/4

Answer 2

1.Add 3c both sides
2.Add 5 both sides
3.divide by 4 both sides.

Answer 3

take variables @ one side & constants @ one side

-3c-c=-5+12 .........(by transformation)
-4c=7
c=-7/4

Answer 4
