Question

evaluate x/y when x+y/y=21​

Answer 1

⭐GIVEN:

• $\bold{\frac{x+y}{y}}$

⭐FIND:

• $\bold{\frac{x}{y}}$

⭐SOLUTION:

here,

$\bold{➔ \frac{x + y}{y} = 21}$

$\bold{➔ \frac{x }{y} + \frac{y}{y} = 21}$

$\bold{➔ \frac{x }{y} + \frac{ \cancel{ y}}{ \cancel{y}} = 21}$

$\bold{➔ \frac{x }{y} + 1 = 21}$

$\bold{➔ \frac{x }{y} = 21 - 1}$

$\bold{➔ \frac{x }{y} = 20}$

⇾Hence, value of $\bold{\frac{x}{y}}$ is 20.
