    You can think of this in terms of money. If I have x dollars, and you have x + 1 dollars, how could we ever have the same amount of money? (If I have 5 dollars, and you have 5+ 1 = 6 dollars, or if I have 100 dollars and you have 100+1 = 101 dollars, etc.) You will always have one dollar more. Algebraically we start with x + 0 = x + 1 ignore the plus zero x = x + 1 subtract x from both sides 0 = 1 ... um. Zero does not equal one. :) So the statement is NEVER true.

    Thank you, I never understood these problems because it's just numbers and letters pulled together. However I do understand now. It's easier once it's explained in money terms. :)
