Simple algebra problem

  1. Feb 18, 2010 #1

    x2 = 0.25

    find x and y

    it's part of a massive physics question, and i'll post the whole thing and my workings so far if it turns out that this maths question is impossible.

    You have two equations in two unknowns, so in theory there is a solution.

    I suggest using the first equation to express y in x (i.e. rewrite x+y=60 to y=60-x), then plug that into the second one and solve the resulting quadratic equation for x.
