First do PEMDAS
There's no parenthesis. So move on to exponent. There's also no exponents. Move on to multiplication. There it is.
12×5=60.
There's no division so now next one is addition. Hey look! There is addition.
60+55=115.
So 115 is your answer.
2*(x-5) = -33, so x-5 = -16.5, so x = -11.5
This is assuming that "the difference between a and b" is a-b, which seems to be the accepted interpretation.
