Question: 4 (2p + 3) = 16 p=?
The line above, 4 (2p + 3) = 16 p=?, means
1) solve the equation, 4 (2p + 3) = 16, for the unknown p.
or,
2) given 4 (2p + 3) = 16, find p.
We have,
4 (2p + 3) = 16 -- divide both sides by 4
(2p + 3) = 4 ----- subtract 3 from both sides
2p = 1 ------------ divide both sides by 2
p = 1/2
