    There is one solution

    Step-by-step explanation:

    sqrt (4x+15) = 3 (sqrt (x))

    divide each side by sqrt (x)

    sqrt (4x+15) / sqrt (x) = 3

    sqrt ((4x+15/x)) = 3

    square each side

    (4x+15) / x = 3^2

    (4x+15) / x = 9

    multiply by x

    4x+15 = 9x

    subtract 4x on each side

    15 = 5x

    divide by 5

    3=x

    Have a Great night!
