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

    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'!

    -3y = 15 is right. now solve for y

    you do that by dividing both sides by the coefficient of y

    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...
