Question

2целых1/3х+1целая 1/2=2целых1/3+1целая2/3х

Answer 1

Пошаговое объяснение:

$2 \frac{1}{3} x + 1 \frac{1}{2} = 2 \frac{1}{3} + 1 \frac{2}{3} x \\ \frac{7}{3} x + \frac{3}{2} = \frac{7}{3} + \frac{5}{3}x \\ 6 \times \frac{7}{3} + 6 \times \frac{3}{2} = 6 \times \frac{7}{3} + 6 \times \frac{5}{3} x \\ 2 \times 7x + 3 \times 3 = 2 \times 7 + 2 \times 5x \\ 14x + 9 = 14 + 10x \\ 14x - 10x = 14 - 9 \\ 4x = 5 \\ x = \frac{5}{4} = 1 \frac{1}{4} = 1.25 \\ \\ \tuburetka$
