Question

2/3x-1/2x+x+2 целых 1/6 = 4,5

Answer 1

$\frac{2}{3} x - \frac{1}{2} x + x + 2 \frac{1}{6} = 4.5\\ \\ \frac{4}{6} x - \frac{3}{6} x + x + 2 \frac{1}{6} = 4.5 \\ \\ 1 \frac{1}{6} x + 2 \frac{1}{6} = 4.5 \\ \\ \frac{7}{6} x = \frac{270}{60} - \frac{130}{60} \\ \\ \frac{7}{6} x = \frac{14}{6} \\ \\ x = \frac{14 \times 6}{6 \times 7} \\ \\ x = 2$
