    x = 2

    Step-by-step explanation:

    set the first equation equal to y

    3y = 6 - x

    multiply by 2

    6y = 12 - 2x

    plug into the second equation

    6x - 6y = 4

    6x - 12 + 2x = 4

    8x - 12 = 4

    8x = 16

    x = 2

    x=2, y = 4/3

    Step-by-step explanation:

    substitute the value of x into the second equation

    move 3y onto the right side.

    x = 6-3y

    now substitute the value of x into the second equation.

    6 (6-3y) + 6y = 4. (solve for y now)

    36 - 18y + 6y = 4

    36 - 12y = 4

    -12y = - 32

    y = 4/3

    put back the value of y into either equation

    x = 6 - 3 (4/3)

    x = 6 - 4

    x = 2
