Answer

$n = -33$ or $n = 13$

Work Step by Step

Let's rewrite the equation so that the variable is on the left side of the equation: $|n + 10| = 23$ To get rid of the absolute value sign, rewrite the equations as two separate equations: $n + 10 = -23$ or $n + 10 = 23$ Subtract $10$ from both sides of the equation: $n = -33$ or $n = 13$
