Answer:

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

Step-by-step 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}}

Hope I helped!

Best regards! :D

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
