Question

X + 1/2 x X = 4/5

Answer 1

`x+1/2 xx x =4/5`

`x xx (1+1/2)=4/5`

`x xx (2/2+1/2)=4/5`

`x xx 3/2=4/5`

`x=4/5:3/2`

`x=4/5xx2/3`

`x=8/15`

Answer 2

\(x+\dfrac{1}{2}\times x=\dfrac{4}{5}\)

\(x\times\left(1+\dfrac{1}{2}\right)=\dfrac{4}{5}\)

           \(x\times\dfrac{3}{2}=\dfrac{4}{5}\)

                  \(x=\dfrac{4}{5}\div\dfrac{3}{2}\) 

                  \(x=\dfrac{8}{15}\)
