Question

104,5*y+14,1*9,6*y=25

Answer 1

\(104,5.y+14,1.9,6.y=25\)

\(104,5.y+135,36.y=25\)

\(y.\left(104,5+135,36\right)=25\)

\(y.239,86=25\)

\(y=25\div239,86\)

\(y=\frac{1250}{11993}\)

y là số vô tỉ nên chị viết thành phân số em nhé!

Answer 2

Giải :

\(104,5.y+14,1.9,6.y=25\)

=> \(104,5.y+135,36.y=25\)

=> \(y.\left(104,5+135,36\right)=25\)

=> \(y.239,86=25\)

=> \(y=25\div239,86\)

=> \(y=\frac{1250}{11993}\)

Answer 3

\(\text{Giải :}\)

\(104,5.y+14,1.9,6.y=25\Rightarrow104,5.y+135,36.y=25\)

\(\Rightarrow y.\left(104,5+135,36\right)=25\)

\(\Rightarrow y.239,86=25\)

\(y=25\div239,86\)

\(\Rightarrow y=\frac{1250}{11993}\)

\(\text{Vậy }y=\frac{1250}{11993}\)
