Question

Solve r/n + t = 4v for r

Answer 1

Since r is being divided by N, we need to multiply both sides by N.
We are left with R + T = 4v/n
Now, we subtract T from each side. The equation is now R = 4V/N - T
We have now solved for R.

Answer 2

r/n+t=4v

r/n+t-t=4v-t

r/n=4v-t

(n)r/n+4v-t(n)

r=4vn-tn

r=n(4v-t)
