    Answer:

    (using substitution to solve the problem)

    x=y-3

    2x+y=12

    2(y-3)+y=12

    2y-6+y=12

    3y=18

    y=6

    y=6

    x=6-3

    = (3, 6)

    Step-by-step explanation:

    using substitution, substitute the x in the second equation to y-3, to find the value of y. after that distribute the 2 into the parenthesis and collect like terms. once you simplify, you have the value of y, so substitute the value of y into the first equation to find x. once you have both values put them in the ordered pair form and you’re done.

    i hope this helps 🙂
