    26/7 = x

    Step-by-step explanation:

    32^ (x + 4) = 64^ (2x-1)

    Rewrite each as a power of 2

    32 = 2^5 and 64 = 2^6

    2^5^ (x + 4) = 2^6^ (2x-1)

    We know a^b^c = a^ (b*c)

    2^ (5 * (x + 4)) = 2^ (6 * (2x-1))

    The bases are the same so the exponents are the same

    5 * (x + 4) = 6 * (2x-1)

    Distribute

    5x + 20 = 12x - 6

    Subtract 5x

    20 = 7x - 6

    Add 6 to each side

    26 = 7x

    Divide by 7

    26/7 = x
