Question

5) 7/9у+ 11/15=3-1/6у
Решите пожалуйста!

Answer 1

7/9у+ 11/15=3-1/6у 
7/9у + 1/6у = 3 - 11/15
14/18у + 3/18у = 2 15/15 - 11/15
17/18у = 2 4/15
у = 2 4/15 : 17/18
у = 34/15 * 18/17
у = 2/5 * 6/1
у = 12/5 = 2,4

Answer 2

7/9у+11/15=3-1/6у
7/9у+1/6у=3-11/15
14/18у+3/18у=2 4/15
17/18у=34/15
у=34/15:17/18
у=12/5
у=2 2/5
