Answer: +7x
Step-by-step explanation: Since both terms contain an <em>x</em>, you can add them together by simply adding their coefficients. Coefficients are just your number in front of your variables. So if -2 + 9 = +7, -2x + 9x = +7x.
Answer:
<u>Remove "x" and add</u>
-2 + 9 = 7
<u>Add "x" back</u>
7 -----> 7x
Note: When adding/subtracting problems like these remove "x" and then add/subtract normaly. When you get your answer put x back.
