7x2 -4x -5x2 +2x = 2x2 -2x
2x^3 - 3x^2 + 4x - 3
4x - 7 = 5 + 7x x = -4
3x + x = 4x
-6 + 3x - y - 4x + 4y + 5 (combine like terms) = (-6 + 5) + (3x - 4x) + (-y + 4y) = -1 - x + 3yHope this helps :)
7x + 6 - 4x = 5 + 2x + 7 subtract 6 from both sides and combine the 5 and 7 on the right: 7x - 4x = 2x + 6 subtract 2x from both sides and combine the 7x and -4x on the left: x = 6
4x + 20
We can simplify this expression by combining the like terms. Here the likes terms are the z's and the x's.2z + 3z + 5z = 10z. (If we have 2 of something and add three of the same thing and then 5 of the same thing we will end up with 10 of that thing).Likewise we can combine the x's.6x - 2x = 4x. (You could think of this as 6x + - 2x if this helps with the idea of "combining".)Therefore we are able to simplify this expression as:2z + 3z + 5z + 4 + 6x - 2x = 10z + 4 + 4x.

x - 2
This would simplify as 4x-5
7x2 -4x -5x2 +2x = 2x2 -2x
(2x-1)(2x-1) = 4x^2 -4x + 1
6x - 4y
It is possible.
