Question

Add. (3b + 5) + (2b + 4)

Answer 1

`\huge{ \fbox{ \sf{5b + 9}}}`

Explanation:

`\star{ \text{( \: 3b + 5) + (2b + 4)}}`

`\text{Step \: 1 \: : \sf{Remove \: the \: unnecessary \: parentheses}}`

`\mapsto{ \sf{3b + 5 + 2b + 4}}`

`\text{Step \: 2 \: : Collect \: like \: terms.}`

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

`\mapsto{ \sf{3b + 2b + 5 + 4}}`

`\mapsto{ \sf{5b + 5 + 4}}`

`\text{ Step \: 3 \: : \sf{Add \: the \: numbers : 5 \: and \: 4}}`

`\mapsto{ \boxed {\sf{ {5b + 9}}}}`

Hope I helped!

Best regards! :D
