Answer:
-x - 3
Step-by-step explanation:
(3x - 4) - (4x - 1) =
The first set of parentheses is unnecessary, so you can just remove it.
= 3x - 4 - (4x - 1)
To remove the second set of parentheses, you must distribute the negative sign to its left by the terms inside the parentheses. To do this, change every sign inside the parentheses.
= 3x - 4 - 4x + 1
Now combine like terms. Terms with x are like terms and are combined together. Therms without x are like terms and are combined together.
= 3x - 4x - 4 + 1
= -x - 3
