Explicación paso a paso:

1) x + 3x – 3 = 6 – 8x – 12 ---   4x + 8x = 6 – 12 +3 ------..--- 12x = - 3  ---x = -3/12     x = - ¼

2) 5x – 5 – 32x + 48 = 6x – 21 – x --- - 27x – 5x = - 21+5-48  --- 22x = - 64     x = -22/-64   x = 11/32

3) 6x + 6 – 20x + 12 = x2 - 3x – x2 + 5 --- -14x + 18 = - 3x +5  --- -14x+3x = 5 – 18 --- -11x= -13   x = 13/11

4) 184 – 2x – 5 = 301 + 6x – 6 – 6 ----  -2x – 6x = 301 – 12 -184 +5 ----- - 8x = 110    x = 110/-8   x = - 55/4

5) 126 – 7x – 18 +30x = - 7x – 9 – 6x – 15 – 12  --- -7x + 30x+7x+6x=-36-126+18 --- 36x = - 144   x=144/36  x=4

6) (12x – 8x +3)/12 = 5x/2  --- 24x – 16x + 6 = 60x  --- 34x-60x = -6  -- -26x = ,6   x = -6/-26  x = 3/13

7) (40x-8x+3)/4 = 2x-6 --- 32x + 3 =8x-24  --- 32x-8x = -24-3   26x = -27   x = -27/26

8) (3x-3-2x+4)/6 = (5x-15+4x-20)/20 ---- (x+1)/6 = (9x-35)/20   ---  20x + 20 = 54x-210 --- 20x-54x = -210-20 -34x = -230    x = 230/34  x = 115/17

9) (4x-8-3x+9)/12 = (x-4)/5  ---  20x – 40 – 15x + 45 = 12x – 48 --- 5x – 12x = -48 +40 – 45   -7x = -53  

  x = 53/7

10) 10x-50x-10 -7 + 5x = 10    - 35x = 27    x = 27/-35     x = - 27/35
