Answer 1

a)

$2(x + 3) > 3(1 - x) \\ 2x + 6 > 3 - 3x \\ 2x + 3x > 3 - 6 \\ 5x > - 3 \\ x > - \frac{3}{5}$

b)

$3(1 - 2x) < 2(x + 1) + x - 7 \\ 3 - 6x < 2x + 1 + x - 7 \\ - 6x - 2x - x < 1 - 7 - 3 \\ - 9x < - 11 \: .( - 1) \\ 9x > 11 \\ x > \frac{11}{9}$

c)

$8(x + 3) > 12(1 - x) \\ 8x + 24 > 12 - 12x \\ 8x + 12x > 12 - 24 \\ 20x > - 12 \\ x > - \frac{12}{20} = - \frac{3}{5}$
