Step-by-step explanation:

Step 1: Define

su = rtv

Step 2: Solve for r

[Division Property of Equality] Divide tv on both sides:                               su/tv = rRewrite/Rearrange:                                                                                         r = su/tv

Making r subject of formula, we get:

r = su/tv

And

Put the value

Put in eq(1)
