Question

If 7y=35/y then find the value of y​

Answer 1

Answer:7y=35y

Y^2=35/7

y^2=5

Y=r5

Y=+-5

Answer 2

Answer:

=>The value of $y = \pm\sqrt{5}$

Step-by-step explanation:

Given expression:

$7y = \frac{35}{y}$

To find:- The value of y,

For determining the value of y, we have to use the concept of DMAS.

By cross multiplication, we get

$=> 7y^2=35$

Divide both the sides by $7$, we get

$=> \frac{7y^2}{7} =\frac{35}{7}$

By further calculating it, we get

$=> y^2=5$

Taking square root n both sides, we get

$=> y = \pm\sqrt{5}$
