Question

Решите уравнения
(9/14+4/7x)/25=1/25

y-7/12y=4 1/6

(5/22+2/11x)*44=16

Answer 1

(9/14+4/7х)/25=1/25
9/14+4/7х=1/25*25
9/14+4/7х=1
4/7х=1-9/14
4/7х=5/14
х=5/14:4/7
х=5/8

у-7/12у=4 1/6
5/12у=25/6
у=25/6:5/12
у=10

(5/22+2/11х)*44=16
5/22+2/11х=16:44
5/22+2/11х=4/11
2/11х=8/22-5/22
2/11х=3/22
х=3/22:2/11
х=3/4
