Question

pls solve : x/(v-5)  -  3x/(v+5)

Answer 1

x/(v-5)-3x/(v+5)
=x(v+5)-3x(v-5)/(v-5)(v+5)
=xv+5x-3xv+15x/v^2-5^2
=20x-2xv/v^2-25
This is the simplified value until you provide some values for x or v or value of the equation.

Answer 2

x/v-5-3x/v+5=x(v+5)-3x(v-5)/(v-5)(v+5)
                     =xv+5x-3xv+15x/(v-5)(v+5)
                     =20x-2xv/(v-5)(v+5)
                     =2x(10-v)/(v-5)(v+5).
