I'll give you 5 stars if correct.

X would be 6 if you add 4.5 + 1.5 then that’s what you get

A/b = 1 would not be a literal equation

if the solution to a  number divided by a number is one then the two numbers would have to be the same

example: 5/5=1 

"a" and "b" are two different numbers so it would be impossible for the solution to equal one
