Respuesta:

$3 + 2(4 + 2x) + 1 = 20 - 2(2 - x) \\ 3 + 8 + 4x + 1 = 20 - 4 + 2x \\ 4x - 2x = 20 - 4 - 3 - 8 - 1 \\ 2x = 4 \\ x = \frac{4}{2} \\ x = 2$

$- 2 - x + 4( - 2x - 3) = - 8x + 1 \\ - 2 - x - 8x - 12 = - 8x + 1 \\ - x - 8x + 8x = 1 + 2 + 12 \\ - x = 15 \\ - 15 = x$

$6(x - 2 + 3x) = - 3( - 4x + 1 - 5) \\ 6x - 12 + 18x = 12x - 3 + 15 \\ 6x + 18x - 12x = - 3 + 15 + 12 \\ 12x = 24 \\ x = \frac{24}{12} \\ x = 2$

$6x = - 4 + x + 3 + 1 \\ 6x - x = - 4 + 3 + 1 \\ 5x = 0$

$x + 2(x + 1) = 4 \\ x + 2x + 2 = 4 \\ x + 2x = 4 - 2 \\ 3x = 2 \\ x = \frac{2}{3}$

$4(x - 3) - 5(x + 2) = 7(3x - 1) + 29 \\ 4x - 12 - 5x - 10 = 21x - 7 + 29 \\ 4x - 5x - 21x = - 7 + 29 + 12 + 10 \\ - 22x = 44 \\ x = \frac{44}{ - 22} \\ x = - 2$

$6x + 2(1 + x) = 3x - 8 + x - 2 \\ 6x + 2 + 2x = 3x - 8 + x - 2 \\ 6x + 2x - 3x - x = - 8 - 2 - 2 \\ 4 x = - 12 \\ x = \frac{ - 12}{4} \\ x = - 3$

$3(4 + 12x) - 6(2x + 3) = 36 + 2(3x + 2) \\ 12 + 36x - 12x - 18 = 36 + 6x + 4 \\ 36x - 12x + 6x = 36 + 4 - 12 + 18 \\ 30x = 46 \\ x = \frac{46}{30} \\ x = \frac{24}{15} = \frac{8}{5}$
