Question 41903: x-6y=11
3y-3x=12
Answer by psbhowmick(878)   (Show Source):
You can put this solution on YOUR website! x - 6y = 11___________(1)
3y - 3x = 12
or y - x = 12/3
or y - x = 4___________(2)
Adding (1) and (2) we can eliminate 'x'.
Thus we have,
y - 6y = 4 + 11
or -5y = 15
or y = -15/5 = -3
Substituting y = -3 in (2) we have
-3 - x = 4
or x = -3 -4 = -7
Answer: x = -7, y = -3
