It is equivalent to: 3x+6+5 = 3x+11

3x-3x+4x^2+8x=4x^2+8x

3x + 2x - 8x + 2x = -x

It is equivalent to: 6x^2 -8x -8

5x+8x+3x-2x = 14x

-8x

-3x + 1

3x+5y+8x+2y combine 3x and 8x to get 11x 11x+5y+2y combine 5y and 2y 11x+7y is the answer.

8x - 23= 3x + 2 +23 +23 8x=3x + 25 -3x -3x 5x=25 x=5 the answer is X=5

3x + 6x - x= 8x

4 + 8x

8x + 6 = 3x - 4 8x = 3x - 4 - 6 8x = 3x - 10 8x - 3x = -10 5x = -10 5x/5 = -10 x = -10/5 x = -2

10 -3x+8x = 25 -3x+8x = 25-10 5x = 15 x = 3

X= -1.8

If: 8x-4 = 3x+21 Then: 8x-3x = 21+4 => 5x = 25 => x = 25/5 Therefore: x = 5

8x + 7

8x

9x + 3x - 9x = 6 + 8x - 113x = 8x - 11-5x = -11x = 2.2 or 11/5

11x + 8 = 8x + 20 3x + 8 = 20 3x = 12 x = 4

(6-4x)(x-2)+3x =6x-12-4x+8x+3x =5x-4

5x2 + 3x + 8x2 = 13x2 + 3x = x(13x + 3)

It is: 30x+80 -8x = 22x+80 when simplified

-2

(3x+1)(2x+2)

It is the same as 8x+2 when simplified
