    m = 1 n = 0

    Step-by-step explanation:

    (2m + n = 2) 2 You need to cancel out one of the variable, so I chose n

    3m - 2n = 3

    3m - 2n = 3

    4m + 2n = 4 Add the two equations together

    7m = 7 Divide both sides by 7

    m = 1

    Plug 1 in for m into one equation

    2 (1) + n = 2

    2 + n = 2

    -2 - 2 Subtract 2 from both sides

    n = 0

    Check this with the other equation to make sure it is the same answer

    3 (1) - 2n = 3

    3 - 2n = 3

    -3 - 3 Subtract 3 from both sides

    -2n = 0 Divide both sides by - 2

    n = 0
