Question

[Giang]

x×4+12×x=55,35

Answer 1

[Duy Nam]

`x \times 4 + 12 \times x = 55,35`

`x \times (4 + 12) = 55,35`

`x \times 16 = 55,35`

`x = 55,35 \div 16`

`x \approx 3,46`

Answer 2

[Nguyễn Gia Khánh]

\(x\times4+12\times x=55,35\)

    \(x\times\left(4+12\right)=55,35\) 

             \(x\times16=55,35\) 

                      \(x=55,35\div16\) 

                     \(x=\dfrac{1107}{320}\)
