    B (3; 6)

    Step-by-step explanation:

    y = x + 3

    4x + y = 18

    4x + (x + 3) = 18

    5x = 18 - 3

    5x = 15

    x = 3

    y = x + 3

    y = 3 + 3

    y = 6

    (3,6)

    Step-by-step explanation:

    We can substitute y for x+3 in the second equation

    4x + x + 3 = 18

    5x = 15

    x=3

    Plug x back into the equation

    y = 3 + 3

    y = 6
