Answer:


\huge{ \fbox{ \sf{x = - 18}}}

Explanation:


\text{4(7x + 3) = - 3(2 - 9x)}


\text{Step \: 1 \: : Distribute \: 4 \: through \: the \: parentheses}


\hookrightarrow{ \sf{28x + 12 = - 3(2 - 9x)}}


\text{Step \: 2 \: : Distribute \: - 3 \: through \: the \: parentheses}


\hookrightarrow{ \sf{28x + 12 = - 6 + 27x}}


\text{Step \: 3 \: : Move \: 27x \: to \: left \: hand \: side \: and \: change \: its \: sign}


\hookrightarrow{ \sf{28x - 27x + 12 = - 6}}


\text{Step \: 4 \: : Move \: 12 \: to \: right \: hand \: side \: and \: change \: its \: sign}


\hookrightarrow{ \sf{28x - 27x = - 6 - 12}}


\text{step \: 5 \: : Collect \: like \: terms}


\text{Like \: terms \: are \: those \: which \: have \: the \: same \: base.}


\hookrightarrow{ \sf{x = - 6 - 12}}


\text{step \: 6 \: : Calculate}


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


\hookrightarrow{ \boxed{ \sf{x = - 18}}}

Hope I helped!

Best wishes ! :D
