Homework Help: How you get the X?

  1. Sep 6, 2010 #1
    1. The problem statement, all variables and given/known data

    I have a formula but i don't know how to get the "X". Example (i need the X): y=1/x => x=1/y.

    This is the formula:

    (1/3)x + (1/4)y = x/a so can someone explain the answer please

    Hi there :)

    Put everything which depends on x on one side of the equal sign; everything which does not depend on x on the other side.
    On the “x” side, factorize so as to have “something” multiplied by x.
    Divide both sides by this “something” :)
