Question

Simplify the expression.
7n + 3(4n-3)-2

Answer 1

`\boxed{ \bold{ \huge{ \boxed{ \sf{19n - 11}}}}}`

Explanation:

`\sf{7n + 3(4n - 3) - 2}`

Distribute 3 through the parentheses

`\longrightarrow{ \sf{7n + 12n - 9 - 2}}`

Collect like terms

`\longrightarrow{ \sf{19n - 9 - 2}}`

The negative integers are always added but posses the negative ( - ) sign

`\longrightarrow{ \sf{19n - 11}}`

Answer 2

Hey there! I'm happy to help!

First we use the distributive property to undo the parentheses.

7n+12n-9-2

We combine the terms with n.

19n-9-2

And we combine the constants.

19n-11.

Have a wonderful day! :D
