/ 13 - 2t / = 15 ÷ 3 ;
/ 13 - 2t / = 5 ;
13 - 2t = + 5 or 13 - 2t = -5 ;
First equation, -2t = - 8; t = 4 ;
Second equation, -2t = - 18 ; t = 9 ;
The solutions are 4 and 9 .

\(3 |13 - 2t | =15\) ⇒ \(|13-2t| = 15\div3\) ⇒ \(\boxed {|13-2t| = 5}\)

\(\hbox {We have two equations : 1. } |13-2t|=5\) 
                                               \(2.|13-2t|=-5\)

\(\hbox{The first: }\) ⇒ \(13-2t=5\) ⇒ \(2t=13-5\) ⇒ \(2t=8\) ⇒ \(\boxed {t=4}\)

\(\hbox { The second: } 13-2t=-5\) ⇒ \(2t=13-(-5)=18\) ⇒ \(\boxed {t=9}\)
