Select the correct answer.
What is the solution for p in the equation?

1/3p + 1/2p = 7/6p +5 + 4

A.
p = -6
B.
p = -1
C.
p = 1
D.
p = 6

Step-by-step explanation:

Problems such as this one become easier to solve if we first eliminate fractions.  Here the LCD is 6 (which is 2 times 3).  

Multiplying all 5 terms by 6, we get:

2p + 3p = 7p + 54, or

5p = 7p + 54.  Then,

-2p = 54, or p = -27

Double check to ensure that you have copied down the last two terms (5 and 4) correctly.
