    B (3,6)

    Step-by-step explanation:

    y = x + 3

    then we will use this y to substitute the other y

    4x + y = 18

    4x + (x + 3) = 18

    4x + x + 3 = 18

    5x = 18 - 3

    5x = 15

    x = 15/5 = 3

    then we can find the value of y

    y = x + 3 = 3 + 3 = 6

    so the (x, y) is (3,6)
