x - y = 9
x + 2y = -6
subtract the two equations simulataneously
-3y = 15
y = -5
now solve for x

- apoorvk

solve these two equations!
subtract the whole of the first equation from the second! the 'x' gets eliminated, and you can find out 'y' then. And use this value of 'y' to get 'x'!

Subtract the two equations what you got??

No need to say thanks...
See, from first equation:
x - y = 9
So here,
x = 9 + y
put y:
x = 9 + (-5)
Now solve for x...
