Answer:
-9x + 3
Step-by-step explanation:
You would distribute first.
− ( x + 3 ) − 2 ( 4x − 3 ) → -x − 3 − 8x + 6
(If you see a negative sign in front of a parenthesis without a number, its usually a negative 1)
From there, you would combine like terms.
-x − 3 − 8x + 6 → -9x + 3
The distance between -3 and 0 is positive 3 , and the distance between 0 and 5 is 5, add 5 and 3 together to get a distance of 8
