Answer:

  • multiplying both sides of the equation by 3
  • substituting 36 for p to check the solution

Explanation:

To undo the division of p by 3, one multiplies by the inverse of 1/3. That is, one multiplies by 3.

Then you have ...

3(p/3) = 3(12)

p = 36 . . . . . simplify

To check this work, you can substitute 36 for p:

36/3 = 12 . . . . . true statement

So, the solution process is ...

multiply both sides of the equation by 3

substitute 36 for p to check the work
