Answer:
-ab+a
Step-by-step explanation:
Remove the parenthesis and change the negative sign between the parenthesis to an addition symbol:
-5ab+a+5+4ab-5
Next, eliminate the opposites:
-5ab+a+5+4ab-5, this will get you:
-5ab+a+4ab
Then, collect the like terms:
-5ab+a+4ab
This will leave you with
-ab+a.
