7x2 -4x -5x2 +2x = 2x2 -2x
-1
5x + 20 = 4x +30 5x - 4x = 30 - 20 x = 10
If your equation is 5x-2=4x+4 Then this is how you solve it... 5x-2=4x+4 5x-2+2=4x+4+2 5x=4x+6 5x-4x=4x-4x+6 x=6 Your x=6
If there are no equals you can simplify this by collecting all the x values together and use the addition property of signed numbers. 2x+4x-5x+x=2x; 4+3=7. 2x+7 is the simplified statement.
-x2+2x
2x2 + (5x-4x)2 + (x-x)2 = 2x2 + x2 + 02 = 2x2 + x2 = 3x2
Simplified: 5+1x
The given expression can be simplified to: 8x squared +9
(5x 2 - 8x + 1) + (2x 2 - 4x - 11)
7x2 -4x -5x2 +2x = 2x2 -2x
The discriminant is 121.
Splitting the equation up into the two variables: x + 4x = 5x -7y + -2y = -9y Therefore, the simplified version is: 5x - 9y

5x+3x-6x+4x+2x-x+10 This expression can be simplified to: 7x+10 (7 being the coefficient of x)
It can be simplified to -4x
- X + 5Y - 4X + 7 gather terms - X - 4X ( same as - X + (- 4X ) 5Y 7 = - 5X + 5Y + 7 ----------------
