Question

if 2x 5y = 500,then x+y is

Answer 1

Answer:

given :- 2x5y = 500.......(i)

$2x = \frac{500}{5y}$

$2x = \frac{100}{y}$

$x = \frac{100}{2y}$

$x = \frac{50}{y} .......(ii)$

putting the value of eq.. (ii )in (i)

$2 \times \frac{50}{y} = \frac{500}{5y}$

$\frac{100}{y} = \frac{500}{5y}$
