*algebra. lmao i spelt it "albebra"!lol

btw, i did type the equation in correctly.

Let's first spilt up the problem:
y+2y-4-y. The first and last "y" cancel each other out.
You now have "2y-4".
Part two: 3y+2-y. The first 3y and the "-y" equal 2y
Now you have a reduced equation of:
2y-4=2y+2
Subtract the 2y from each other and you'll have:
-4=2, and that's not right, so there are no (real) answers to this equation

There isn't one. All the y's cancel out, leaving the following nonsense:
- 4 = + 2, or 6 = 0.
So not only is there no solution for y, one can't even say that "any y will satisfy this equation." NO value of y can make make this equation true. It's inconsistent, pure and simple.
Live long and prosper.

Are you sure you typed it in correctly? Because as far as I can tell, there is no solution to that problem.
You would combine like terms:
y+2y-y would combine to form 2y
3y-y would form 2y
therefore:
2y-4=2y+2
are you seeing the problem here?
subtract 2y from both sides, and:
-4=2
clearly not true, therefore, there is no solution to the problem you typed.

There is no value of y that will make that equation correct.
(edit to David) You might want to recheck your figures and recheck the equation as written.
It appears to me that you missed one of the y values in the original equation. I suspect that when you were copying the original equation you may have missed one of the y values.
That is why you are getting a different answer than most of the other responders to this question.

y + 2y - 4 - y = 3y + 2 - y
2y - 4 = 2y + 2
-4 = 2 {no equation here}

move y's to one side and changes signs as necessary
y+2y-y-3y=2+4
-y=6
therefore
y= -6
your being tought to watch out for changing signs when moving from 1 side of = to other

take y as a factor for both sides
y(1+y-4-1)=y(2y+2-1)
divided by Y
y-4=2y+1
y-2y=-4+1
-y=5
y=-5

y+2y-y=2y
3y-y=2y
==>>-4=2
=> r u having fun?

bring all y's on one side of the equation
1y+2y-1y+1y-3y=+4+2
3y-3y=6
0=6

No answer. The variable y cancels out.
