Here we go,
[tex] \frac{4}{  |p| }  + 12 = 14[/tex]
Subtract 12 from both sides,
[tex] \frac{4}{ |p| }  + 12 - 12 = 14 - 12 \\  \frac{4}{ |p| }  = 2[/tex]
Multiply both sides with |p|
[tex] \frac{4}{ |p| }  \times  |p|  = 2 \times  |p |  \\ 4 = 2 \times  |p| \\ [/tex]
divide both sides with 2
[tex] \frac{4}{2}  =  \frac{(2 \times  |p| )}{2}  \\ 2 =  |p| [/tex]
Therefore,
|p| equals  2.
