Question

Solve |p + 2| = 10

Answer 1

To solve an absolute value equation like this, use the following:
X is an expression is x, in this case, in p.
b is a number
|X| = b
X = b or X = -b
Just set what is inside the absolute value sign equal to 10 and equal to -10.
Separate the equations with the word "or."
Solve both equations.

Answer 2

\[|p+2| =10 \rightarrow p+2 = \pm10\]
\[p+2 = 10 or p+2=-10 \rightarrow p = 8 or p =-12\]
