Given that r cannot equal 0 and r=5w=7a, find the value of r-w in terms of a

Value of r-w in terms of a is:

r-w=

Step-by-step explanation:

We are given that:

r=5w=7a

We have to find the value of r-w in terms of a

r-w=5w-w   (Since r=5w)

    = 4w

   =   (Since, 5w=7a)

   =

Hence, Value of r-w in terms of a is:

r-w=
