Answer:


\huge{ \fbox{ \sf{x = 5}}}

Explanation:


\star{ \sf \: - 8 = 12 - 4x}


\text{Step \: 1 \: : Swap \: the \: sides \: of \: the \: equation}:


\mapsto{ \sf{12 - 4x = - 8}}


\text{Step \: 2 \: : Move \: 12 \: to \: right \: hand \: side \: and \: change \: its \: sign}


\mapsto{ \sf{ - 4x = - 8 - 12}}


\text{Step \: 3 \: : Calculate}


\text{ \underline{Remember ! }} : \sf{ \: The \: negative \: integers \: are \: always \: added \: but \: posses \: the \: negative \: ( - ) \: sign.}


\mapsto{ \sf{ - 4x = - 20}}


\text{Step \: 4 \: : Divide \: \: both \: sides \: by \: 4}


\mapsto{ \sf{ ( - 4x)/( - 4) = ( - 20)/( - 4)}}


\text{Step \: 5 \: : Calculate}


\mapsto{ \sf{x = 5}}

Hope I helped!

Best regards! :D
