    1. find a common multiple for the denominators of both fractions.

    2. combine the fractions together. do not expand the numerator first.

    3. cross multiply.

    4. expand the terms

    5. make x the subject.

    Here is a better way.
    Perform the indicated multiplications and combine terms

    (2/5)(20x+5) - (1/2)(8-4x) = 38
    8x +2 -4 +2x = 38
    10x = 40
    x = 4
