Question

Can anyone help me and give me a example please!

Answer 1

I hope I can help!

So, first if all, you have to combine like terms.

You can use shaped to help you combine the like terms.

So, it would be -9x + 12x then 7 - 15

-9x + 12x = 3x
7 - 15 = 8

3x - 8

Example:

5x + 6x + 7 + 7

Combine like terms

5x + 6x = 11x
7+7=14

11x + 14 would be your answer

Have a great day/evening/night! :)
Let me know if you have any additional questions!
