Question

1)(x-23):26=8 2)1728:(56-x)=36

Answer 1

1)
(х - 23) : 26 = 8
х - 23 = 8 * 26
х - 23 = 208
х = 208 + 23
х = 231
проверка:
(231 - 23 ) : 26 = 8
208 : 26 = 8
8 = 8

2)
1.728 : (56 - х) = 36
56 - х = 1.728 : 36
56 - х = 48
- х = 48 - 56
- х = -8
х = 8
проверка:
1.728 : (56 - 8) = 36
1.728 : 48 = 36
36 = 36
