Resposta:

$a) \: 2x + 1 < x + 6 \\ 2x - x < 6 - 1 \\ x < 5 \\ b) \: 2 - 3x > x + 14 \\ 2 - 14 > x + 3x \\ - 12 > 4x \\ x < \frac{ - 12}{4} \\ x < - 3 \\ c) \: 2(x + 3) > 3(1 - x) \\ 2x + 6 > 3 - 3x \\ 2x + 3x > 3 - 6 \\ 5x > - 2 \\ x > \frac{ - 2}{5} \\ d) \: 3x - 11 < 2(x + 1) \\ 3x - 11 < 2x + 1 \\ 3x - 2x < 1 + 11 \\ x < 12 \\ e) \: 5x + 12 < 2x + 36 \\ 5x - 2x < 36 - 12 \\ 3x < 24 \\ x < \frac{24}{3} \\ \\ x < 8 \\ f) \: x - 2 > - x + 4 \\ x + x > 4 + 2 \\ 2x > 6 \\ x > \frac{6}{2} \\ \\ x > 3 \\ g) \: 5x - 10 < 15 \\ 5x < 15 + 10 \\ 5x < 25 \\ x < \frac{25}{5} \ \ \\ x < 5 \\ h) \: 6x + 3 < 3x + 18 \\ 6x - 3x < 18 - 3 \\ 3x < 15 \\ x < \frac{15}{3} \\ x < 5 \\ i) \: 8x + 3 > 12 - x \\ 8x + x > 12 - 3 \\ 9x > 9 \\ x > \frac{9}{9} \\ x > 1 \\ j) \: 2x + 10 > - x + 25 \\ 2x + x > 25 - 10 \\ 3x > 15 \\ x > \frac{15}{3} \\ \\ x > 5$
