Answer 1

x=-8 y=10

Explanation:

Rewrite equations:

1/2x+1/2y=1;1/3x+1/4y=-1/6

1/2x+1/2y+1

1/2x+1/2y=1

subtract both sides by(-1)/2y

1/2x+1/2y+(-1/2y)=1+(-1/2y)

1/2x=-1/2y+1

divide both sides by 1/2

1/2x/1/2=-1/2y+1/1/2

x=-y+2

substitue -y+2 for x in 1/3x+1/4y=-1/6

1/3x+1/4y=-1/6

1/3(-y+2)+1/4y=-1/6

-1/12y+2/3=-1/6

simplify both sides of the equation

-1/12y+2/3+-2/3=-1/6+-2/3

add (-2)/3 to both sides

-1/12y=-5/6

-1/12y/-1/12=-5/6/-1/12

divide both sides by (-1)/12

y=10

substitue 10 for y in x=-y+2

x=-y+2

x=-10+2

x=-8
