# If m = 2, then find the value of $\dfrac{5m}{2}+4$  Hint: We have to solve the given expression which is in terms of m and we have the value of m. Just put the value of m in the expression $\dfrac{5m}{2}+4$ and then solve it further.

According to the question, it is given that the value m is equal to 2 and we have to find the value of the expression $\dfrac{5m}{2}+4$ .
We can see that the expression is in terms of m and we also have the value of m.
m = 2 …………………..(1)
$\dfrac{5m}{2}+4$ ……………………….(2)
To get the value of the given expression we have to put the value of m in equation (2).
Now, putting the value of m in equation (2), we get,
\begin{align} & \dfrac{5m}{2}+4 \\ & =\dfrac{5\times 2}{2}+4 \\ \end{align}
On solving further, we get
\begin{align} & =\dfrac{10}{2}+4 \\ & =5+4 \\ & =9 \\ \end{align}
Hence, the value of the expression given in the question $\dfrac{5m}{2}+4$ is obtained as 9.

Note:In this question, one might forget to add 4 after putting the value of m in $\dfrac{5m}{2}$ . If we do so, then our answer is wrong because our expression is $\dfrac{5m}{2}+4$ . So, we have to add 4 after putting the value of m in $\dfrac{5m}{2}$ . After substituting m = 2, one can also cancel 2 as it is common in the numerator and denominator. Then, we will have 5 + 4 which will directly result in 9.
