Answer :
The answer would be -2x + 8.
3 - x - (x - 5)
3 - x - x + 5
3 + (-x - x) + 5
3 - 2x + 5
(-2x + 8).
3 - x - (x - 5)
3 - x - x + 5
3 + (-x - x) + 5
3 - 2x + 5
(-2x + 8).
(-x+3) - (x-5)
-x+3-x+5 (subtraction sign changes all signs within the parentheses)
-2x + 8 (combine variables and constants)
-x+3-x+5 (subtraction sign changes all signs within the parentheses)
