    x = 2

    y = 0

    Step-by-step explanation:

    We can solve using substitution, substitute y in the first equation with the second equation:

    - (-6x + 12) + 3x = 6

    Distribute the negative sign:

    6x - 12 + 3x = 6

    Combine like terms:

    9x - 12 = 6

    Isolate the variable and solve for x by adding 12 in both sides:

    9x = 18

    x = 2

    Substitute 2 with x in any equation to find the value of y:

    -y + 3 (2) = 6

    -y + 6 = 6

    Subtract 6 in both sides to isolate the variable:

    -y = 0

    0/-1 = 0

    y = 0

    Our answer would be x = 2 and y = 0

    (2,0)

    Step-by-step explanation:

    I'm going to use substitution since one of the variables in one of the equation is already solved for.

    -y+3x=6

    y=-6x+12

    I'm going to replace the first y with the second y which is (-6x+12).

    This gives me:

    - (-6x+12) + 3x=6

    Distribute:

    6x-12+3x=6

    Combine like terms:

    9x-12=6

    Add 12 on both sides:

    9x=18

    Divide both sides by 9:

    x=2

    If x=2 and y=-6x+12, then y=-6 (2) + 12=-12+12=0.

    The solution (the intersection) is (2,0).
