Step-by-step explanation:

15 = |x| - 5

|x| - 5 = 15

|x| = 15 + 5

|x| = 20

x = ±20

x = -20 or 20

Option → B

[tex]\large\boxed{\mathsf{15 = |x| - 5}}\\\large\boxed{\mathsf{|x| - 5 = 15}}\\\large\boxed{\textbf{ADD 5 to BOTH SIDES}}\\\large\boxed{\mathsf{\rightarrow |x| - 5 + 5 = 15 + 5}}\\\large\boxed{\textbf{CANCEL out: -5 + 5 because it gives you 0}}\\\large\boxed{\textbf{KEEP: 15 + 5 because it help solve for the x-value}}\\\large\boxed{\textbf{NEW EQUATION: }\mathbf{|x| = 15 + 5}}\\\large\boxed{\textbf{SIMPLIFY IT!}}\\\large\textbf{Possibility \#1: x = 20}\\\large\textbf{or even Possibility \#2: x = -20}[/tex]
