Question

Решите уравнения: 4 5/23+х =10 2/23,
7 9/16-(х-2 3/16)=4 11/16

Answer 1

4 5/23 + х = 10 2/23
х = 10 2/23 - 4 5/23
х = 9 25/23 - 4 5/23
х = 5 20/23
Проверка: 4 5/23 + 5 20/23 = 10 2/23
                  9 25/23 = 10 2/23
                  10 2/23 = 10 2/23

7 9/16 - (х - 2 3/16) = 4 11/16
х - 2 3/16 = 7 9/16 - 4 11/16
х - 2 3/16 = 6 25/16 - 4 11/16
х - 2 3/16 = 2 14/16
х = 2 14/16 + 2 3/16
х = 4 17/16
х = 5 1/16
Проверка: 7 9/16 - (5 1/16 - 2 3/16) = 4 11/16
                  7 9/16 - (4 17/16 - 2 3/16) = 4 11/16
                  7 9/16 - 2 14/16 = 4 11/16
                  6 25/16 - 2 14/16 = 4 11/16
