Question

Solve. t=p+3r/6 for r

Answer 1

t = p + 3r/6
So we are looking for r.
Then our first step is to rewrite this as follows.
t - 3r/6 - t = p - t + 3r/6 - 3r/6
Now we have:
-3r/6 = p - t
That gets all the terms except r on the left.
Now if we multiply everything by 6, we have:
-3r = 6(p-t)
Which expands to:
-3r = 6p - 6t
Divide through by -3 and we have:
-3r/-3 = (6p-6t)/-3
r = -2p + 2t
