Answer 3

:) Thankssss. I got it.

Answer 4

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.

Answer 5

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. :)
