∙ 13y agoSolve for x:
3x - y = -9 is the same as 3x + 9 = y
Since you now know the equation for y you can plug it into the first equation:
3x - (3x + 9) = -9
After solving, you will also see that x cancels out and that -9 = -9.
Solve for y:
3x - y = -9 is the same as y/3 - 3 = x
Since you now know the equation for x you can plug it into the first equation:
3(y/3 - 3) - y = -9
After solving, you will also see that y cancels out and that -9 = -9.
The Answer:
There are actually two posibble answers:
1.) y = -9 and x = 0
If you plug the numbers in then you will get 3(0) + (-9) = -9
The answer is -9 = -9
2.) y = 0 and x = -3
If you plug the numbers in then you will get 3(-3) + (0) = -9
This will also give you the answer -9 = -9
