$if \: x = 1 \div x5 \sqrt{5 \: \: find \: the \: value \: of \: x2 + 1 \div x2} }$
​

Answer 1

If X+1=X , then what is the value of X? The simple answer is that X has no value. The problem is unsolvable. One of the first things they teach when you learn about algebra and the use variables in mathematics is that you can take a number on one side of the equation and move it to the other side.
