Answer:


\huge \boxed { \boxed{x = \{6 , - 6 \}}}

Explanation:

to understand this

you need to know about:

  • absolute value
  • equation
  • PEMDAS

tips and formulas:

  • |a|=±a

let's solve:


  1. \sf divide \: bothe \: sides \: by \: 5 : \\ ( 5|2x| )/(5) = (60)/(5) \\ |2x| = 12

  2. \sf seperate \: the \: equation \:in \: 2 \:parts : \\ \begin{cases}2x = 12 \\ \: 2x = - 12\end{cases}

  3. \sf \: di vide \: both \: sides \: by \: 2 : \\ \begin{cases} (2x)/(2) = (12)/(2) \\ \: (2x)/(2) = ( - 12)/(2) \end{cases} \\ \therefore x = \{6 , - 6 \}
