    x = 1, y = - 4

    Step-by-step explanation:

    Given the 2 equations

    y = - 7x + 3 → (1)

    y = - x - 3 → (2)

    Substitute y = - x - 3 into (1)

    - x - 3 = - 7x + 3 (add 7x to both sides)

    6x - 3 = 3 (add 3 to both sides)

    6x = 6 (divide both sides by 6)

    x = 1

    Substitute x = 1 into either of the 2 equations for value of y

    Substituting in (2)

    y = - 1 - 3 = - 4
