Answer:
Ans: x=0
y= -2
Step-by-step explanation:
-6x+y= -2--------- (1) × 6
-3x-6y= 12--------(2) × 1
-36x+6y= -12-----(3)
-3x-6y= 12--------(2)
(3)+(2)
-36x+6y+(-3x-6y) = -12+12
⇒ -36x+6y-3x-6y = 0
⇒ -36x-3x = 0
⇒ -39x=0
⇒ x= 0/-39
∴ x = 0
Substitute x = 0 into (1)
-6x+y= -2
⇒-6(0)+y= -2
⇒0+y= -2
∴y = -2
Ans: x = 0
y = -2
Check:
-6x+y= -2--------- (1)
= -6(0)+(-2)
= 0 - 2
= -2 ✔
-3x-6y= 12--------(2)
= -3(0)-6(-2)
= 0+12
= 12 ✔
