Answer 1

Answer is x + 12

Explanation:

Hello! Recall that you have to write clear questions in order to get exact answers. So I'll help you assuming that the two expressions are the following:

First expression:

$2x+9$

Second expression:

$x-3$

So the operation we need to perform is:

$2x+9-(x-3)$

Recall some rules:

$(+)\times (+)=+ \\ \\ (-)\times (-)=+ \\ \\ (-)\times (+)=- \\ \\ (+)\times (-)=-$

Hence:

$2x+9-(x-3)=2x+9-x+3 \\ \\ \\ Combine \ like \ terms: \\ \\ (2x-x)+(9+3) \\ \\ \boxed{x+12}$
