Question

2/3x-1/2x+x+2 целых 1/6 = 4,5

Answer 1

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