7c? - 17 = 6c - 15

Solve

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

Move the 6c over to the 7c side

1c - 17 = - 15

Then move the - 17 over to the - 15 side

C=2
