Answer:

\huge{ \fbox{ \sf{12x - 28}}}

Step-by-step explanation:

\star{ \sf{ \:  \: 4(5x - 6) - 4(2x + 1)}}

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

\mapsto{ \sf{20x - 24 - 4(2x + 1)}}

\text{Step \: 2 \:  : Distribute \: 4 \: through \: the \: parentheses}

\mapsto{ \sf{20x - 24 - 8x - 4}}

\text{Step \: 3 \:  : Collect \: like \: terms}

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

\mapsto{ \sf{20x - 8x - 24 - 4}}

\mapsto{ \sf{12x - 24 - 4}}

\text{Step \: 4 \:  : Calculate}

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

\mapsto{ \sf{12x - 28}}

Hope I helped!

Best regards! :D
