    What do you do to powers when you are dividing? Use this fact to form an equation with involving x and you should be able to solve for x

    That's the part that confuses me, I really don't understand it.

    as everything is a power of 2 you can compare the powers. when you divide numbers with powers you subtract the powers (if there is a common coefficient). this means we can say that 3x - (x-5) = 17.

    3x - x +5 = 17.

    You can finish the rest

    When you divide powers you subtract them if you have the same coefficient. In this case the coefficient is 2 which means the powers of the numbers, once subtracted will equal 17
