5x - 3 + 2x + 7 = ?7x + 5 = ?
2x2+5x+3 = (2x+3)(x+1) when factored
2x +1 = 5x-2 2x +3= 5x 3 = 3x x=1
Depending on how the problem is written. 2x + 3 - 5x + 10 -3x + 13 ■ Or... 2x + 3 - (5x + 10) -3x - 7 ■ I think you want the second answer.
(2x+3)/(10x2+21x+9)Factor the quadratic expression in the denominator:(2x+3)/(5x+3)(2x+3)which becomes:1/(5x+3) or (5x+3)-1

6 + 2x = 5x + 9 , 6 - 9 = 5x - 2x , -3 = 3x , x = -1
Depending on how the problem is written. 2x + 3 - 5x + 10 -3x + 13 ■ Or... 2x + 3 - (5x + 10) -3x - 7 ■ I think you want the second answer.

3x + 5x = 2x + 28x = 2x + 26x = 2x = (2/6) = 1/3
(2x + 3)(x + 1 ) = 2x^2 +5x +3
5x+7 = 2x-3 5x-2x = -3-7 3x = -10 x = -10/3
2x + 7 + 5x - 4 - x = (2x + 5x - x) + (7 - 4) = 6x + 3
-5x+3(x+8)=16-2x
If: x+9+5x = 21+2x Then: x = 3
