Well depending on the equation you look at both sides and eliminate everything from both using addition, subtraction, multiplication, and division.
Ex:
3c-4=7 first add the 4 because you use the opposite type of operation so you add it to 7 which gives you:
3c=11 next you have to divide to get it alone
3c/3=11/3
which gives you
c= 3.66666666667
