Question

x+7/15=14/15, a-4/5=1/5

Answer 1

Ответ:

$x = \frac{7}{15}$; $a = 1$

Пошаговое объяснение:

$x + \frac{7}{15} = \frac{14}{15}\\\\x = \frac{14}{15} - \frac{7}{15}\\\\x = \frac{7}{15}$

$a - \frac{4}{5} = \frac{1}{5}\\\\a = \frac{1}{5} + \frac{4}{5}\\\\a = 1$

Answer 2

x+7/15=14/15, х= 14/15-7/15; х=7/15

a-4/5=1/5; а=1/5+4/5; а=1
