Answer:
The solution is the point (-12,8)
Step-by-step explanation:
we have
-x-y=4 ----> equation A
x+2y=4 ----> equation B
Adds equation A and equation B and solve for y
-x-y=4
x+2y=4
---------------
-y+2y=4+4
y=8
Find the value of x
x+2y=4
x+2(8)=4
x=4-16
x=-12
therefore
The solution is the point (-12,8)
