Answer 2

$3 |x| - 1 = 14 \\ 3 |x| = 14 + 1 \\ 3 |x| = 15 \\ |x| = 15 \div 3 \\ |x | = 5 \\ x_{1} = - 5 \\ x_{2} = 5</p><p>$

$(3x - 2)(x + 4) = 0 \\ 3x - 2 = 0 \\ 3x = 2 \\ x = \frac{2}{3} \\ \\ x + 4 = 0 \\ x = - 4$

$- 3(x + 1) = 4x + 11 \\ - 3x - 3 = 4x + 11 \\ - 3x - 4x = 11 + 3 \\ - 7x = 14 \\ x = 14 \div ( - 7) \\ x = - 2$

$x - 5(6 - x) = 2x - 2 \\ x - 30 + 5x = 2x - 2 \\ x + 5x - 2x = 30 - 2 \\ 4x = 28 \\ x = 28 \div 4 \\ x = 7$
