Ok, 4x+1-5x=5-(x+4). Could someone help me with this one? I came up with x=-4 but the answer is "all real numbers" I don't see how they got that? All my odd-numbered problems are in the back of the book but they don't show you how to get to the solution:) Denise, Help!

Solving the left side:
4x+1-5x = -x+1
Solving the right side:
5-(x+4)
= 5-x-4
= 1-x which can be written as -x+1
Now lets compare:
-x+1 = -x+1
Same equations on both side thus the answer is all real numbers.
