Slve this system by elimination: 8x+5y=22
6x+ 2y=13

  • Algebra 2 - ,

    In the second equation,

    x=4y+6 Put that in the first equation for x, and solve for y.

    In the second system, multipy the first equation by 2, and the second by 5
    16x+10y=24
    30x+10y=44
    Now subtract one equation from the other.
