4,6 x y + y + 4,4 x y = 2017
4,6 x y + y x 1 + 4,4 x y = 2017
( 4,6 + 1 + 4,4 ) x y = 2017
10 x y = 2017
y = 2017 : 10
y = 201,7
4,6 x y +y +4,4 x y =2017
(4,6 + 4,4 ) x y + y = 2017
9 x y + 1 x y = 2017
(9 + 1 ) x y =2017
10 x y = 2017
y = 2017 : 10
y = 201,7
4,6 x y + 6,4 x y = 0,32
=>y x (4,6 + 6,4 )= 0,32
=>y x 11=0.32
=>y=0.32:11
=>y=8/275
y x 1,2 + y x 4,6 + y x 5,2 = 18
y x ( 1,2 + 4,6 + 5,2 ) = 18
y x 11 = 18
y = 18 : 11
y = \(\dfrac{18}{11}\)
Y x 1,2 + Y x 4,6 + Y x 5,2 = 18
Y x (1,2 + 4,6 + 5,2) = 18
Y x 11 = 18
Y = 18 : 11
Y = \(\dfrac{18}{11}\)
`y xx 3,2 + 6,8 xx y = 68,84 + 4,6`
`y xx ( 3,2 + 6,8 ) = 73,44`
`y xx 10 = 73,44`
`y = 73,44 : 10`
`y = 7,344`
y x (3,2 + 6,8) = 73,44
y x 10 = 73,44
y = 73,44 : 10
y = 7,344
a. y x 4/7 = 6/35
y = 6/35 :4/7
y = 3/10
b. y : 4,6 = 10,2
y= 10,2x4,6
y= 46,92
a. \(y.\frac{4}{7}=\frac{6}{35}\)
\(y=\frac{6}{35}:\frac{4}{7}\)
\(y=\frac{3}{10}\)
b.\(y:4,6=10,2\)
\(y=10,2.4,6\)
\(y=46,92\)
\(A=0,36.350+0,9.45.4+3.20.12\)
\(A=0,36.350+0,36.45+3,6.20\)
\(A=0,36.350+0,36.45+0,36.10.20\)
\(=0,36.\left(350+45+20.10\right)\)
\(A=0,36.595\)
\(A=214,2\)
\(b.12,8.3,2-y:4,6=35,06\)
\(40,96-y:4,6=35,06\)
\(y:4,6=40,96-35,06\)
\(y:4,6=5,9\)
\(y=5,9.4,6\)
\(y=27,14\)
\(4,6\times y+y+4,4\times y=2017\)
\(y\text{}\times\text{}\left(4,6+1+4,4\right)=2017\)
\(y\text{ }\times10=2017\)
\(y\text{ }=2017:10=201,7\)
4,6 x y + y +4,4 x y = 2017
=> (4,6+4,4)*y=2017
=. 9*y=2017
=> y= \(\frac{2017}{9}\)
