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
