Question

Решите уравнение:
2) y + 1/4 = 4/5 - 3/10
4) 2/3 - ( 2/9 + x ) = 1/3​

Answer 1

$2)y + \frac{1}{4} = \frac{4}{5} - \frac{3}{10} \\ y + \frac{1}{4} = \frac{1}{2} \\ y = \frac{1}{2} - \frac{1}{4} = \frac{2 - 1}{4} = \frac{1}{4}$

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

Answer 2

Ответ:

y+1/4=4/5-3/10

y=1/4=1/10

y=1/10-1/4

y

Пошаговое объяснение:

y+1/4=4/5-3/10

y=1/4=1/2

y=1/4-1/2

y=2
