Answer 1

9 1/5-(5х-4 112)=8 14/14*11 1/4=201/2=100 1/2
9 1/5-5х+4 1/2=100 1/2
-5х=100 1/2-4 1/2-9 1/5=96-9 1/5=84 4/5
х=-16 24/25

(10у+45у)/24=5 1/18-3 2/9
(55/24)*у=11/6
55у=44
у=44/55=4/5

Answer 2

1)9,2- 5x*4/45+9/2 * 4/45=8  14/15
9,2+0,4-8  14/15 =4x/9
2/3=4x/9
x=1,5

2)5y/12+15y/8=5  1/18  - 3  4/18
55y/24=33/18
y=12/15
y=0,8
