    2x+y=1
    3x-y=14
    Answer: (3,5)
    ------------------------
    Hey, you can check easily. Just put the values in for x and y
    2(3)+5 = 8 not 1 - NO WAY

  • Algebra 2/Math -

    on the last

    4a+3b=6
    24a-3b=-27 ( I multiplied by 3), then add
    28a=-19

    why did you get no solution?

    others are correct.
