yx110-y:0,125-y:0,5=5,702
yx110-yx8-yx2 =5,702
yx(110-8-2) =5,702
yx100 =5,702
y =5,702:100
y =0,05702
\(y\times110-y:0,125-y:0,5=5,702\)
\(y\times110-y\times8-y\times2=5,702\)
\(y\times\left(110-8-2\right)=5,702\)
\(y\times100=5,702\)
\(y=5,702:100\)
\(y=0,05702\)
Vậy...............
![](https://rs.olm.vn/images/avt/0.png?1311)
y x 110 - y : 0,125 - y : 0,5 = 5,702
=>y x 110 - y x 8 - y x 2 = 5,702
=>y x ( 100 - 8 - 2 )= 5,702
=>y x 100 = 5,702
=> y = 5,702 : 100
=> y =0,05702
Vậy y = 0,05702
HOK TỐT
Ta có:
\(y\times110-y:0,125-y:0,5=5,702\)
\(\Leftrightarrow y\times110-y:\frac{1}{8}-y:\frac{1}{2}=5,702\)
\(\Leftrightarrow y\times110-y\times8-y\times2=5,702\)
\(\Rightarrow y\times\left(110-8-2\right)=5,702\)
\(\Rightarrow y\times100=5,702\)
\(\Rightarrow y=\frac{5,702}{100}\)
\(\Rightarrow y=0,05702\)
Vậy \(y=0,05702\)

a) y x 8 + y : 0,5 = 9,78
y x 8 + y x 2 = 9,78
y x ( 8 + 2 ) = 9,78
y x 10 = 9,78
y = 9,78 : 10
y = 0,978
b) 92 . x + x : 0,125 = 746,2
92 . x + x . 8 = 746,2
x . ( 92 + 8 ) = 746,2
x . 100 = 746,2
x = 746,2 : 100
x = 7,462

0,25 x y = 0,125 + 0,5
0,25 x y = 0,625
y = 0,625 : 0,25
y = 0,25
vậy x = ...
