Question

is x+1=1 always sometimes or never true

Answer 1

sometimes

Answer 2

how so? just trying to understand this for summer school, didn't think it would haunt me.

Answer 3

x=2 2+1 doesnt = 1

Answer 4

its not true

Answer 5

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.
