Answer:
-5x,-3x, and 9x
Step-by-step explanation:
these are like terms because they all have an x at the end. say there was a number like 7xb and 6xb, they would be like terms, however, if you have 3x and 3xb, they would not be like terms. When you have like terms you can combine them together. So for this, it would be
1x+4
hope this helps :)
