Question

Решите уравнение с дробями четн 2,4,6​

Answer 1

2)

(5/12-х) : 1/2=2/9

(5/12-х)×2=2/9

5/6-2х=2/9

-2х=2/9-5/6

-2х=-11/18

х=11/36

4)

4/15-(у+3/26)=1/25

4/15-у-3/25=1/25

11/75-у=1/25

-у=1/25-11/75

-у= - 8/75

у=8/75

6)

3 1/16÷(х-5/16)=7/8

49/16÷(х-5/16=7/8

49/16×16х-5/16=7/8

49×1/16х-5=7/8

392=7(16х-5)

56=16х-5

-16х+56=5

-16х= -61

х=61/16
