12c - 53 = 91

First add 53 to each side.  This cancels it out on the left (-53 + 53 = 0)

12c = 91 + 53
12c = 144

Now divide by 12 on each side.  This cancels the 12 on the left (12/12 = 1)

c = 144/12
c = 12

Hi Zack

12c-53=19

Add 53 to both sides

12c-53+53=91+53

12c=144

Divide both sides by 12

12c/12= 144/12

c= 12

I hope that's help !
