    x = 2, y = - 11

    x=2, y = - 3

    Step-by-step explanation:

    -4x-3 = - 2x+1

    -4x+2x = 1 + 3

    -2x = 4

    x = 2

    use The first function

    y = - 4 (2) - 3

    y = - 8-3

    y = - 11

    (2, - 11)

    use The second function

    y = - 2 (2) + 1

    y = - 4+1

    y = - 3

    (2, - 3)
