    X = 0

    y = 2

    2x + 3y = 6

    -5x + 2y = 4

    Multiply the first equation by 2

    (2x + 3y = 6) 2 =

    4x + 6y = 12

    Then multiply the 2nd equation by - 3

    (-5x + 2y = 4) - 3

    That equals

    15x - 6y = - 12

    Then add the two equations together

    4x + 6y = 12

    15x - 6y = - 12

    That equals

    4x = 0

    Balance

    x = 0

    Now let's plug x into the first equation

    2 (0) + 3y = 6

    That equals

    3y = 6

    Balance

    y = 2
