Question

Evaluate the expression $\frac{5x+15}{10}+\frac{4x+3}{5}$ for $x=3.$

Answer 1

$\underset{–}{\text{Need to Evaluate:}}$

$\frac{5x+15}{10}+\frac{4x+3}{5}$ for $x=3.$
Now, in the above expression, after replacing $x$ with $3,$ we get:

$\Rightarrow \frac{5\times 3+15}{10}+\frac{4\times 3+3}{5}$

$\Rightarrow \frac{15+15}{10}+\frac{12+3}{5}$

$\Rightarrow \frac{30}{10}+\frac{15}{5}$

$\Rightarrow 3+3=6$

Therefore, the value of the expression $\frac{5x+15}{10}+\frac{4x+3}{5}$ for $x=3$ is $6.$
