Question

3u/u+8=3/5 solve and verify

Answer 1

Answer:

Value of u = 2

Step-by-step explanation:

$\frac{3u}{u+8}=\frac{3}{5}$

$\implies 5\times 3u = 3(u+8)$

$\implies 15u = 3u+24$

$\implies 15u - 3u = 24$

$\implies 12u = 24$

$\implies u = \frac{24}{12}$

$\implies u = 2$

Therefore,

Value of u = 2

Answer 2

Given:

$\frac{3u}{u+8}=\frac{3}{5}$

To Find:

The value of "u" = ?

Solution:

On applying cross-multiplication in the above given equation, we get

⇒  $3u\times 5=3(u+8)$

⇒  $15u=3u+24$

On subtracting "3u" from both sides, we get

⇒  $15u-3u=3u+24-3u$

⇒  $12u=24$

⇒  $u=\frac{24}{12}$

⇒  $u=2$

So that the value of "u" will be "2".
