Answer 2

Let x = 2. The solution of x + 4/3x is $\frac{14}{3}$

Solution:

Given expression is $x+\frac{4}{3} x$

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

Let say expression $x+\frac{4}{3} x$ be represented by f(x)

$\Rightarrow \mathrm{f}(x)=x+\frac{4}{3} x$ --- 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  

$\begin{array}{l}{\Rightarrow \mathrm{f}(2)=2+\frac{4}{3} \times 2} \\\\ {=>\mathrm{f}(2)=\frac{14}{3}}\end{array}$

Hence value of expression $x+\frac{4}{3} x$ at x = 2 is  $\frac{14}{3}$
