Thread: Solve 4 + 3 / 4 + x - 1 / 4 = 1

  1. #1

    Solve 4 + 3 / 4 + x - 1 / 4 = 1

    I keep getting this equation wrong
    x + 3/4 + x - 1/4 = 1
    This is my working out:
    4(x+3) + 4(x-1) = 1
    4x+12 + 4x-4 = 1
    4x + 4x = 1 + 4 - 12
    8x = -7
    I'm pretty sure I'm doing something wrong but I don't know where.

    Not clear what this is. [tex]\dfrac{x+3}{4} + \dfrac{x-1}{4} = 1[/tex]? Is that it?


    [tex]x + \dfrac{3}{4} + x - \dfrac{1}{4} = 1[/tex]? Or is that it?

    In any case, multiply EACH TERM (both sides of the equation) by 4 and simplify. One term at a time.

    Multiply BOTH sides by 4.

    Keep in mind that [(a + b) / c] * c = a + b
