    3x^2 / 4 = 48

    Multiply both sides by 4 to get rid of the four on the left.

    3x^2 = 192

    Divide both sides by 3

    x^2 = 64

    The square root 64 to get x

    Remember there are two answers

    x = 8 and x = -8

    Answer:

    x = 8

    Explanation:

    \frac{3x^2}{4} =48

    multiply both sides by 4: 3x^2=192

    divide both sides by 3: x^2=64

    take the square root:

    \sqrt{x^2} = \sqrt{64} \\x=8
