Question

(45,8-y)x2,8=46,06

Answer 1

`(45,8-y)xx2,8=46,06`

`=>45,8-y=46,06:2,8`

`=>45,8-y=16,45`

`=>y=45,8-16,45`

`=>y=29,35`

Answer 2

`(45,8-y)xx2,8=46,06`

`=> 45,8-y=46,06:2,8`

`=> 45,8-y=16,45`

`=> y= 45,8 -16,45`

`=>y=29,35`

Answer 3

(45,8 - y) x 2,8 = 46,06

⇒128,24 - 2,8y = 46,06

⇒ 2,8y = 128,24 - 46,06y 

⇒ 2,8y = 82,18

⇒ y = 82,18 : 2,8

⇒ y = 29,35

Answer 4

\(\left(45,8-y\right)\times2,8=46,06\\ \rightarrow45,8-y=46,06:2,8\\ \rightarrow45,8-y=16,45\\ \rightarrow y=45,8-16,45\\ \rightarrow y=29,35\)

Answer 5

\(\left(45,8-y\right)\times2,8=46,06\\ \rightarrow45,8-y=46,06:2,8\\ \rightarrow45,8-y=16,45\\ \rightarrow y=45,8-16,45\\ \rightarrow y=29,35\)
