Simplify 4(5x - 6) - 4(2x + 1) 12 x - 5 12 x - 20 12 x - 28

Answer 1

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

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
