Answer:
Reorder the terms:
-17 + 7c = 6c + -15
Reorder the terms:
-17 + 7c = -15 + 6c
Solving
-17 + 7c = -15 + 6c
Solving for variable 'c'.
Move all terms containing c to the left, all other terms to the right.
Add '-6c' to each side of the equation.
-17 + 7c + -6c = -15 + 6c + -6c
Combine like terms: 7c + -6c = 1c
-17 + 1c = -15 + 6c + -6c
Combine like terms: 6c + -6c = 0
-17 + 1c = -15 + 0
-17 + 1c = -15
Add '17' to each side of the equation.
-17 + 17 + 1c = -15 + 17
Combine like terms: -17 + 17 = 0
0 + 1c = -15 + 17
1c = -15 + 17
Combine like terms: -15 + 17 = 2
1c = 2
Divide each side by '1'.
c = 2
Simplifying
c = 2
