Question 256383
If we use x for the unknown number, then the problem translates to:
{{{x - 10 = sqrt(2) + x}}}
If we subtract x from each side of this equation we get:
{{{-10 = sqrt(2)}}}
The variable x has disappeared! This means that there is either no solution to the equation or that <b>any</b> number works for x in the equation. Since {{{-10 = sqrt(2)}}} is a false statement, this tells us that there is no solution to this problem. (If the equation had worked out to be a true statement, like 6 = 6 or {{{sqrt(2) = sqrt(2)}}} then this would mean that all numbers work.
