Question

Решите уравнение 1 ) 9/16-×=1/2
2)×+2/3=7/8
3)1/2+×=23/24
4)×-3/8=1/4

Answer 1

9/16 - х = 1/2
х = 9/16 - 1/2 = 9/16 - 8/16
х = 1/16
------------------------------------
х + 2/3 = 7/8
х = 7/8 - 2/3 = 21/24 - 16/24
х = 5/24
-------------------------------------
1/2 + х = 23/24
х = 23/24 - 1/2 = 23/24 - 12/24
х = 11/24
--------------------------------------
х - 3/8 = 1/4
х = 3/8 + 1/4 = 3/8 + 2/8
х = 5/8

Answer 2

1) 1/16
2) 5/24
3) 11/24
4) 5/8
