Question

2 7/9x - 1 3/4 = 2 5/12​

Answer 1

Ответ:

1,5

Пошаговое объяснение:

(2 7/9)x - 1 3/4 = 2 5/12​

25х/9 - 7/4 = 29/12

25х/9 = 29/12 + 7/4

25х/9 = 50/12

х=6/4=1,5

Answer 2

Пошаговое объяснение:

2 7/9х - 1 3/4 = 2 5/12

2 7/9х = 2 5/12 + 1 3/4

2 7/9х = 2 5/12 + 1 9/12

2 7/9х = 3 14/12

2 7/9х = 4 2/12

2 7/9х = 4 1/6

25/9х = 25/6

х = 25/6 : 25/9

х = 25/6 * 9/25

х = 1/2 * 3/1

х = 3/2

х = 1 1/2
