    (x - 2) log(7) = x * log(5) x * log(7) - x * log(5) = 2 log(7) x [log(7) - log(5)] = 2 log(7) x [log(7) - log(5)] = 2 log(7) x = 2 log(7) / [log(7) - log(5)] = log(49) / log(7/5) ≈ 11.57

    16^x-4 = 3^3-x (x-4)log16 = (3-x)log3 xlog16 - 4log16 = 3log3 - xlog3 xlog16 + x log3 = 3log3 + 4log16 x = (3log3 + 4log16) / (log16 + log3)

    I don't have those types of calculators, it was my teacher that tried helping me out with the first one.
