Answer :
-2(2x-y)=-1
3x-2y=1
-4x+2y=2
3x-2y=1
-x=3 (x=-3)
(-3,__)
2(-3)-y=-1
-6-y=-1
-y=-1+6
-y=5
y=-5
so..(-3,-5)
3x-2y=1
-4x+2y=2
3x-2y=1
-x=3 (x=-3)
(-3,__)
2(-3)-y=-1
-6-y=-1
-y=-1+6
-y=5
y=-5
so..(-3,-5)
2x-y=-1 (1)
3x-2y=1 (2)
(1) * 2--> 4x-2y=-2 (3)
(3) - (2)
x= -3
sub x= -3 into (1)
2(-3)-y=-1
-6-y=-1
-y=5
y= -5
3x-2y=1 (2)
(1) * 2--> 4x-2y=-2 (3)
(3) - (2)
x= -3
sub x= -3 into (1)
2(-3)-y=-1
-6-y=-1
-y=5
y= -5
