-3x-5y=-6
6x+5y=-34
how do i solve this using elimination?

  • algebra - ,

    First you add the equations.
    -5y and 5y cross each out so you are left with 3x=-40
    X= -40/3
    Plug x back into one of the equations
    -3x-5y=-6
    -3(-40/3)-5y=-6
    -40-5y=-6
    -5y= 34
    Y=34/-5

    Correction: It should be positive 40-5y=-6
    So -5y=-46
    Y=46/5
