    x=2 y=2

    Step-by-step explanation:

    Rewrite equations:

    -6x-y=-14; 3x+2y=10

    Step: Solve-6x-y=-14for y:

    -6x-y=-14

    -6x-y+6x=-14+6x (Add 6x to both sides)

    -y=6x-14

    -y

    -1

    =

    6x-14

    -1

    (Divide both sides by - 1)

    y=-6x+14

    Step: Substitute-6x+14foryin3x+2y=10:

    3x+2y=10

    3x+2 (-6x+14) = 10

    -9x+28=10 (Simplify both sides of the equation)

    -9x+28+-28=10+-28 (Add - 28 to both sides)

    -9x=-18

    -9x

    -9

    =

    -18

    -9

    (Divide both sides by - 9)

    x=2
