    Answer: (-2, 1)

    Step-by-step explanation:

    y = x + 3

    y = 2x + 5

    Using substitution, replace "y" in the second equation with what y equals in the first equation:

    x + 3 = 2x + 5

    3 = x + 5

    -2 = x

    Now substitute "x" with - 2 and solve for y

    y = (-2) + 3

    y = 1
