Answer 1

$1)4x - 5 > 3x + 11 \\ 4x + 3x < 11 + 5 \\ 7x < 16 \\ x < 16 \div 7 \\ x < 2.28.. \\ \\ 2)x + 2x < 3x + 6 \\ 3x > 3x + 6 \\ 3x - 3x > 6 \\ x > 6 \\ \\ 3)x + 8 < 20 + 2 \\ x + 8 < 22 \\ x > 22 - 8 \\ x > - 7.9 \\ \\ 4)3x - 1 < - 7 \\ 3x < - 7 - 1 \\ 3x < - 8 \\ x < - 8 \div 3 \\ x < - 0.33$
