Question

Solve for p q=1/2p+15

Answer 1

Ok, let's see what we got here, q=1/2p+15, solve for p, here's the steps:
q=1/2p+15
-15       -15
q-15=1/2p
*2      *2
2q-30=p, or you can write it as p=2q-30

*I multiplied two at the last step because 2 is the reciprocal of 1/2, it just gonna make it more confusing if you divide it by 1/2, so the best solution here is to multiplies 1/2 by it reciprocal, which is 2.

Answer 2

q=1/2p+15
1/2p = q - 15
     p = 2q - 30

hope it helps
