2x-5y=13, 5x-3y= -15 can anyone show me how to find out the value of x , y please,thanks

  • mat/simultaneous equation - ,

    I would use elimination here

    1st times 3 ---> 6x - 15y = 39
    2nd times 5 --> 25x - 15y = -75
    subtract them:
    -19x = 114
    x = -6

    back into 1st
    -12 - 5y = 13
    -5y = 25
    y = -5

    x = -6 , y = -5
