    x = - 2 y = - 4

    Step-by-step explanation:

    3x - 2y = 2 - > 15x - 10y = 10

    5x - 5y = 10 - > 15x - 15y = 30

    Substract one equation from another:

    15x - 15x - 10y + 15y = 10 - 30

    5y = - 20

    y = - 4

    Plug in y into an equation

    3x + 8 = 2

    3x = - 6

    x = - 2
