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

4 5/23 + х = 10 2/23х = 10 2/23 - 4 5/23х = 9 25/23 - 4 5/23х = 5 20/23Проверка: 4 5/23 + 5 20/23 = 10 2/23                  9 25/23 = 10 2/23                  10 2/23 = 10 2/237 9/16 - (х - 2 3/16) = 4 11/16х - 2 3/16 = 7 9/16 - 4 11/16х - 2 3/16 = 6 25/16 - 4 11/16х - 2 3/16 = 2 14/16х = 2 14/16 + 2 3/16х = 4 17/16х = 5 1/16Проверка: 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
