Answer 2

Let x = 2. The solution of x + 4/3x is
`(14)/(3)`

Solution:

Given expression is
`x+(4)/(3) x`

Need to evaluate above expression when value of x is 2.

Let say expression
`x+(4)/(3) x` be represented by f(x)

`\Rightarrow \mathrm{f}(x)=x+(4)/(3) x` --- equation 1

As we need to evaluate value of f(x) when x = 2, we need value of f(2)

To get f(2) lets substitute x = 2 in equation 1

`\begin{array}{l}{\Rightarrow \mathrm{f}(2)=2+(4)/(3) * 2} \\\\ {=>\mathrm{f}(2)=(14)/(3)}\end{array}`

Hence value of expression
`x+(4)/(3) x` at x = 2 is
`(14)/(3)`
