Answer 2

The value of $\dfrac{x+y}{x-y}$ is equal to 5.

Step-by-step explanation:

Given,

x : y = 3 : 2

To find, $\dfrac{x+y}{x-y}$ = ?

∴ x : y = 3 : 2

⇒ $\dfrac{x}{y} =\dfrac{3}{2}$

∴ $\dfrac{x+y}{x-y}$

Dividing numerator and denominator by y, we get

$=\dfrac{\dfrac{x+y}{y} }{\dfrac{x+y}{y}}$

$=\dfrac{\dfrac{x}{y}+1}{\dfrac{x}{y}-1}$

Put $\dfrac{x}{y} =\dfrac{3}{2}$, we get

$=\dfrac{\dfrac{3}{2}+1}{\dfrac{3}{2}-1}$

$=\dfrac{\dfrac{3+2}{2}}{\dfrac{3-1}{2}}$

= $\dfrac{5}{1}$

= 5

∴ The value of $\dfrac{x+y}{x-y}$ = 5

Thus, the value of $\dfrac{x+y}{x-y}$ is equal to 5.
