5x + 10 - 2x - 3x + 2 + 4x = 0
5x - 2x - 3x + 4x + 10 + 2 =0
5x - 5x + 4x + 12 = 0
0 + 4x + 12 = 0
4x = - 12
x = - 12/4
x = - 3
11 - x - 3 = 4x + 3 + 2 + 4x
- x + 8 = 8x + 5
8x + x = 8 - 5
9x = 3
x = 3/9
x = 1/3

[5x-2x-3x+4x+10+2=0] [-x-4x=-11+3
[4x+12=0] [-5x=-8 .(-1)
[[4x= -12] [5x=8]]
20x²+32x=-60x-96
20x²+32x+60x+96=0

[5x+10-2x-3x+2+4x=0][11-x-3=4x]
[4x + 12 = 0][-4x - x + 8 = 0]
[4x = -12][-5x = -8] = -20x = 96 ==> x = -4,8
