Question

решите уравнение 5/12y+1,3=0,53+7/8y

Answer 1

5/12y + 1,3 = 0,53 + 7/8y
7/8y - 5/12y = 1,3 - 0,53
21/24y - 10/24y = 0,77
11/24y = 0,77
y = ( 77/100 ) : ( 11/24 ) = ( 7•24)/100 = 168/100 = 1,68
Ответ 1,68

Answer 2

5/12y+1,3=0,53+7/8y; 5/12у-7/8у=0,53-1,3; 10/24у-21/24у=-0,77; -11/24у=-77/100; У=77/100*24/11; У=84/50=1,68=1 34/50
