    (3, 2) is the ordered pair for the given system of equations.

    Step-by-step explanation:

    Given:

    2 x + y = 8 ... (i)

    y = - x + 5 ... (ii)

    Put y = - x + 5 in equation (i) -

    2 x + ( - x + 5) = 8

    2 x - x + 5 = 8

    x = 8 - 5

    x = 3

    Now put x = 3 in equation (ii) -

    y = - 3 + 5

    y = 2

    Hence the (3, 2) is the correct ordered pair.
