    a=3x+b/4-x

    Step-by-step explanation:

    I dont know which variable you're supposed to solve for. But here's how i got the answer above:

    Divide each term in a (4-x) = 3x+b by 4-x

    a (4-x) / 4-x=3x/4-x+b/4-x

    Then, cancel the common factor of 4-x, giving you

    a=3x/4-x+b/4-x

    Finally, combine the numerators over the common denominator,

    giving you a=3x+b/4-x
