Question

Tìm y: y x 3 + y x 4 + y : 3 + y : 4 = 182

Answer 1

\(y\times3+y\times4+y:3+y:4=182\\ y\times3+y\times4+y\times\dfrac{1}{3}+y\times\dfrac{1}{4}=182\\ y\times\left(3+4+\dfrac{1}{3}+\dfrac{1}{4}\right)=182\\ y\times\dfrac{91}{12}=182\\ y=182:\dfrac{91}{12}\\ y=24\)

Answer 2

`yxx3+yxx4+y:3+y:4=182`

`yxx3+yxx4+yx 1/3+yx1/4=182`

`yxx(3+4+1/3+1/4)=182`

`yxx 91/12=182`

`y=182: 91/12`

`y=182xx12/91`

`y=24`

Vậy `y=24`
