Question

Solve rx = 30 for x.

Question 2 options:

x = 30/r


x = 30r


x = 30 - r


x = 30 + r

Here, rx = 30
Just divide r from both sides, so it would get canceled from Left hand side
x = 30 / r

In short, Your Answer would be Option A

Hope this helps!

rx = 30...divide both sides by r
x = 30/r <==
