Question 5890
plug in 4,-4 to verify:
{{{-1/3*4-4/3*-4=-2}}}
{{{-4/3-(-16/3)=-2}}}
{{{12/3=-2}}} not true (incorrect answer)

multiply both equations by 3 to clear the denominators:
-x-4y=-6
x-2y=12

add them together:
-6y=6
y=-1

substitute -1 in for y:
-x-4y=-6
-x-4(-1)=-6
-x+4=-6
-x=-10
x=10

substitute x=10 and y=-1 into the other equation to verify:
x-2y=12
10-2(-1)=12
10+2=12  true statement, so the solution is (10,-1)
