Question

Решить уравнение 5/9-х=1/3. Х+2/3=1 1/2

Answer 1

$1) \frac{5}{9} - x = \frac{1}{3} \\ x = \frac{5}{9} - \frac{1}{3} = \frac{5}{9} - \frac{3}{9} \\ x = \frac{2}{9}$

$x + \frac{2}{3} = 1 \frac{1}{2} \\ x = 1 \frac{1}{2} - \frac{2}{3} = 1 \frac{3}{6} - \frac{4}{6} = \frac{9}{6} - \frac{4}{6}$

$x = \frac{5}{6}$

Answer 2

1) 2/9;

2) 5/6.

Пошаговое объяснение:

1)

5/9 - х = 1/3

5/9 - х = 3/9

х = 5/9 - 3/9

х = 2/9

ответ: 2/9.

2)

х + 2/3 = 1 1/2

х = 1 1/2 - 2/3

х = 1 3/6 - 4/6

х = 9/6 - 4/6

х = 5/6

ответ: 5/6
