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

Question

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

Answer 1

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
