Answer 1

Ответ:

$3x - 3 = 2 - 2x \\3x + 2x = 2 + 3 \\ 5x = 5 \\ x = 1 \\ \frac{7}{6} x - \frac{3}{6} = \frac{5}{2} x + \frac{1}{2} \\ \frac{7}{6} x - \frac{5}{2} x = \frac{1}{2} + \frac{3}{6} \\ \frac{7}{6} x - \frac{15}{6} x = \frac{3}{6} + \frac{3}{6} \\ - \frac{8}{6} x = \frac{6}{6} \\ - \frac{4}{3} x = 1 \\ x = 1 \div - \frac{4}{3} \\ x = \frac{1}{1} \times - \frac{3}{4} \\ x = - \frac{3}{4}$
