Question

a) 431 - x = 97;
б) y + 7,83 = 15,9;
в) 10 3/5 - x = 4 1/4;
г) 7/8z = 1.

Answer 1

Ответ:

а.

$431 - x = 97 \\ x = 431 - 97 \\ x = 334$

б.

$y + 7.83 = 15.9 \\ y = 15.9 - 7.83 \\ y = 8.07$

в.

$10 \frac{3}{5} - x =4 \frac{1}{4} \\ 10.6 - x = 4.25 \\ x = 10.6 - 4.25 \\ x = 6.35$

г.

$\frac{7}{8z} = 1 \\ \\ 8z = \frac{7}{1} = 7 \\ \\ z = \frac{7}{8}$
