CAN ANYONE PLEASE HELP ME I HAVE NO CLUE WAT TO DO AND I AM SO CONFUSED HELP ANYONE PLEASE

4x-5y=-19
2x+17=y

what is the solution of the system?

  1. Reiny

    I would use substitution here.
    your second equation describes what y is
    It said y = 2x+17
    so sub that into the first

    4x + 5y = -19
    4x + 5(2x+17) = -19
    4x + 10x + 85 = -19
    14x = -104
    x = -104/14
    x = 52/7
