do you mean
Is this correct?
Solve for x.
a) 2^x+2-2^x =96
2^x (2^2 +2) =96 nvm i did addition instead of subtraction i see my mistake... on this question.
x=4 (the answer at the back of the book says its 5)
c) 4^x+1 +4^x=160
(the answer is suppose to be 2.5 but i dont see where they are coming from.)
