Answer:
3x + 4
Step-by-step explanation:
First we want to remove the parentheses so
4x + 3 - (x-1)
4x + 3 -x +1 The signs changed because of the negative sign that was distributed in the parentheses
now arrange them
4x - x + 3 + 1
Now solve
4x - x = 3x
3 + 1 = 4
The answer is 3x + 4
Hope this helps :)
