3c-5=2c+5

You would want to do 3c - 2c and that would equal 1c. So that would leave you with 1c - 5 = 5.

So you would do 5 (before the =) and you would bring that 5 to the 5 on the other side of the equal sign. You would do 5+5 (inverse operation)

then that would leave you with 1c=10. You would divide 10 into 1 and that would equal 10 so... the answer would be:

c= 10
