    one number = x another - y now, just read the problem... x+y=72 2(x-y)=24 solve the system for z & y - your numbers

    I got 12 for x. Am I on the right track?

    x+y=72 x-y=12 2x=72+12=84 so x=84/2=42

    y=72-x x-(72-x)=12 x-72+x=12 2x=12+72 2x=84 x=42

    So, how would I find the other number? Plug it in?
