    1.) 6x=12

    x=2

    3 (2) + 3y=-9

    6+3y=-9

    3y=-3

    y=-1

    (2,-1)

    2.) 7x=-35

    x=-5

    5x+2y=-19

    5 (-5) + 2y=-19

    -25+2y=-19

    2y=-44

    y=-22

    (-5,-22)

    3.) 4x=-16

    x=-4

    2 (-4) + 3y=1

    -8+3y=1

    3y=-7

    y=-7/3

    (-4,7/3)

    4.) 7x=35

    x=5

    2 (5) + 3y=-5

    10+3y=-5

    3y=5

    y=5/3

    (5,5/3)

    5.) 2x=-8

    x=-4

    x+4y=4

    -4+4y=4

    4y=0

    y=1

    (-4,1)
