Math page 167 algebra did you hear about...

posted by .

Hi I need help with this one problem. It's on page 167 algebra with pizzazz. It has to use the addition method.
3x-5y=7
5x-2y=-1

    How do you start it then I can solve it easily. I'm not cheating.!!!!!

    You want either the x's or the y's to have opposite coefficients.
    let's work on the y's

    #1 times 2 ----> 6x - 10y = 14
    #2 times -5 ---> -25x + 10y =5
    add them:
    -19x = 19
    x = -19/19 = -1
    back in #1:
    3(-1) - 5y = 7
    =5y = 7 + 3 = 10
    y = -2

    x = -1 , y = -2
