Answer:

Explanation:
Hello.
First, think of the minus sign as being -1.
Now, multiply -1 times 5 and -4x.
-1 times 5 is -5
-1 times -4x is 4x
Put them together:
-5+4x (this expression can't be simplified anymore, because -5 and 4x aren't like terms)
And we're done!
I hope it helps & have an outstanding day!
