Answer:
-7
Explanation:
First you plug all the terms in. Once you've done that, you realize what tou have is -5-4 -1+-3
First you solve the first part (-5-4) and get -9.
Then you solve the second half (1+-3) and get -2
You then have the equation -9--2
But because you're subtracting a negative, it turns into a positive.
So now our equation is -9+2
And you get -7.
