Answer: -5a + 3b
Step-by-step explanation:
3a + 2b - 8a + b
Start with writing the like terms next to each so that you don't get confused:
3a - 8a + 2b + b
Now, simply the 'a' variable to get:
-5a + 2b + b
Finally simplify the 'b' variable to get:
-5a + 3b
The above expression cannot be simplified further as they do not have any common terms. Therefore, the expression -5a + 3b is in it's simplest form.
