Question

Do X=0 mean the same thing as no solution.

Answer 1

No. If 0+x=0, then 0 is the answer. No solution would be an example of x+2=x-2 when x=2. 2+2≠2-2

Answer 2

No because if it was no solution you would put I solution or a 0 with a line through it. 0 is still a number just like -1 -2 and -3 are still a number;) hope this helps
