    (1, 2)

    Step-by-step explanation:

    Given the 2 equations

    y = - 3x + 5 → (1)

    y = 4x - 2 → (2)

    Substitute y = 4x - 2 into (1)

    4x - 2 = - 3x + 5 (add 3x to both sides)

    7x - 2 = 5 (add 2 to both sides)

    7x = 7 (divide both sides by 7)

    x = 1

    Substitute x = 1 into (2) for corresponding value of y

    y = (4 * 1) - 2 = 4 - 2 = 2

    Solution is (1, 2)
