Question

if x/y=m/n prove 5x+7y/5x-7y=5m+7n/5m-7n using componendo and dividendo

Answer 1

Step-by-step explanation:

Here we have the equation x/y = m/n

Now multiply by 5 both sides and divide my 7 both the sides we will get,

5x / 7y = 5m / 7n

Now by componendo dividendo rule , we will get.

5x + 7y / 5x -7y = 5m + 7n / 5m - 7n

HOPE THIS WILL HELP YOU.
