First of all we will remove the brackets on the right side
In front of the bracket there is a minus sign (-) so that means that when we will remove the brackets, the sign inside the bracket will change from + to - and vice versa
so we will have: 15=5-c-7
lets put c in one side and the numbers on the other side
c=5-7-15
c=-17
