You can put this solution on YOUR website! In this problem it looks like they want you to solve for c. 68 + 2c = 180.
 First we need to simplify and isolate the c term on the left side. We do this by subtracting 68 from both sides.
 68 (-68) + 2c = 180 (-68)
 0 + 2c = 112
 2c = 112
 Now to solve for c we simply divide each side by 2
 2c/2 = 112/2
 The 2's divide out and we are left with
 c = 56.
 Now, let's check our solutions by plugging it back into the original equation.
 
 68 + 2(56) = 180
 68 + 112 = 180
 180 = 180. It checks out so c = 56 is the correct answer.
