Answer:
x=-1
Step-by-step explanation:
6+4x-2y=0
2(3+2x-y)=0
3+2x-y=0
2x-y= -3......equation 1
-3-7y=10x
-3=10x+7y......equation 2
from equation 1
5×(2x-y= -3)=
10x-5y=-15.....equation 3
from equation 2and 3
(10x-5y=-15)-(10x+7y= -3)
-12=-12y
therefore, y=1
from equation 1
2x-y=-3
2x-1=-3
2x=-3+1
2x=-2
x=-2/2=-1
