Question

5p+9c=p for c

Answer 1

How do you think you would start?

Answer 2

I say I would multiply the p on both sides.

Answer 3

If you multiplied p on both sides, that would give you:\[p \times (5p + 9c) = p \times (p)\]Which is \[5p^{2} + 9pc = p^{2}\] Doing that would make things more difficult. What would you do instead of multiplying both sides by p?

Answer 4

I start with the 5p

Answer 5

I got it the answer is c=-4p/9
