Chapter 7: Q15. (page 247)

Find the value of x.
$\frac{x + 2}{x + 3} = \frac{4}{5}$

Short Answer

Expert verified

The value of x is2 .

Step by step solution

Step 1. Given information.

The ratio here given is,

$\frac{x + 2}{x + 3} = \frac{4}{5}$

Step 2. Concept and Formula Used.

The properties of proportion,

if $\frac{a}{b} = \frac{c}{d}$ then $a d = b c$ ,

The given ratio is $\frac{x + 2}{x + 3} = \frac{4}{5}$ ,

Step 3. Use the property of proportion, if ab=cd then,ad=bc .

Then,

$\begin{array}{l} 5 (x + 2) = 4 (x + 3) \\ 5 x + 10 = 4 x + 12 (Usingdistributiveproperty) \\ 5 x - 4 x = 12 - 10 \\ x = 2 \end{array}$

Therefore, the value of x is 2.
