    Answer:

    x = 1

    y = 3

    Step-by-step explanation:

    2x + 1 = y ——- eqn (1)

    2y = 6——–eqn (2)

    from eqn(2)

    2y = 6

    y = 3

    when you divide 6 by 2y

    substitute y = 3 into eqn (1)

    2x + 1 = y

    2x + 1 = 3

    2x = 3-1

    2x = 2

    therefore

    x = 1
