Question

Помогите пожалуйста!!!

Answer 1

Ответ:

2) x = 2

3) x = -22, x = 32

Пошаговое объяснение:

$2.\\ frac{x+2}{3} - 1 = frac{x+6}{12}-frac{x}{6}\\frac{x}{3}+frac{2}{3}-1 = frac{x}{12} + frac{6}{12} - frac{x}{6}\\frac{x}{3} - frac{x}{12} + frac{x}{6} = 1-frac{2}{3}+frac{6}{12}\\frac{4x-x+2x}{12} = frac{1}{3} + frac{1}{2}\\frac{5x}{12} = frac{5}{6}\\5x = frac{12cdot 5}{6}\\5x = 10\x = 2$

$3.\\6|x-5| = 162\\|x-5| = 27 Leftrightarrow left [begin{array}{lcl} {{x-5=27, ;;x geq 5} \ {x-5=-27, ; x < 5}}end{array} right. Leftrightarrow left [begin{array}{lcl} {{x=32} \ {x=-22}}end{array} right.$
