Can someone show me step by step on how to factor/solve this problem explaining the steps?

5.50 = (0.02x^3 + 5x) / x

  • Math -

    expand the terms on the right:
    5.50 = 0.02x^2/x + 5x/x

    reduce the fractions:
    5.50 = 0.02x + 5

    subtract 5 from both sides:
    0.50 = 0.02x

    divide by 0.02 (or multiply by 50):
    25 = x
