    (-2, 5)

    Step-by-step explanation:

    I will assume that your system is

    y = - 4x - 3

    y = - 2x + 1

    Multiplying the second equation by - 2 results in

    y = - 4x - 3

    -2y = 4x - 2

    combining these two equations eliminates x temporarily:

    -y = - 5, so that y must be 5.

    Substituting 5 for y in the second equation, we get:

    5 = - 2x + 1, or

    4 = - 2x, which results in x = - 2

    and so the solution is (-2, 5)
