    Answer:

    y = 16, don’t know if I’m 100% right but hope this helps.

    Step-by-step explanation:

    since they both equal Y they may be equal to each other

    Then you would subtract 2x from both sides canceling it out on one side

    2x + 8 = 5x – 4

    -2x         -2x

    This would make the equation 8 = 3x – 4

    next you add the 4 from both sides

    8  = 3x – 4

    +4         +4

    This will leave you with 12 = 3x

    now you divide 3 from both sides and 12/3 = 4 makes X = 4

    next you take (4) and plug it in to one of the equations

    y = 2(4) + 8

    y = 8 + 8

    y = 16
