    Step-by-step explanation:

    Given the 2 equations

    y = - x + 2 → (1)

    y = - 2x - 1 → (2)

    Using substitution method.

    Substitute y = - x + 2 into (2)

    - x + 2 = - 2x - 1 (add 2x to both sides)

    x + 2 = - 1 (subtract 2 from both sides)

    x = - 3

    Substitute x = - 3 into (1)

    y = - ( - 3) + 2 = 3 + 2 = 5

    Solution is ( - 3, 5)
