Solve uing the subtitution method. Show your work. If the system has no solution or an infinite number of solutions, stat this,3x-15y=-12
3x+24y=-12

  • intermediate algebra -

    3x-15y=-12 ...(1)
    3x+24y=-12 ...(2)
    Subtract (1) from (2) to get
    39y=0, or y=0.
    Substitute into (1) and get
    3x+0=-12,
    or x=-4
