For y we have the problem y=3(3)-5 and we get 9-5 which is 4 so y=4
What about y
Ok so you multiply the 2 to the parenthesis and the problem becomes 2x+4y=4 over 2x+4y=4. Everything crosses out and the answer is 0=0.
The problem is 2(x=2y=2) over 2x+4y=4.
Ya, I can do it.
Are you ready for the last one.
Ok, thats easy.
So the last is pretty easy and it is a one solution.
So first i can bring the 3x-5 down to the y and the problem is 3x-5=(-x)+7. We can add the 5 to both sides and we get 3x=(-x)+12 and we can add the x to 3x to get 4x, so we have 4x=12. if we divide on both sides we get x=3.
