Answer:

\boxed{  \bold{ \huge{ \boxed{ \sf{14x + 4}}}}}

Step-by-step explanation:

\sf{(5x + 2) - ( - 9x - 2)}

When there is a ( - ) sign in front of an parentheses in an expression , change the sign of each term in the expression. Also, remove the parentheses

\dashrightarrow{ \sf{5x + 2  + 9x + 2}}

Collect like terms

\dashrightarrow{ \sf{14x + 2 + 2}}

Add the numbers : 2 and 2

\dashrightarrow{ \sf{14x + 4}}

Hope I helped!

Best regards! :D
