    y = 5 and x = - 3

    Step-by-step explanation:

    Given,

    y = x + 8 ... (equation 1)

    x + y = 2 ... (equation 2)

    Now, by substituting the value of y in equation 2, we get;

    ⇒ x + x + 8 = 2

    ⇒ x = - 3

    and now, by substituting the value of x in equation 1, we get;

    ⇒ y = - 3 + 8

    ⇒ y = 5
