if jessica solved an equation and her answer was o=2 , explain to jessica what her result means

Answer 1

is that supposed to say 0 = 2 ?

in that case it means that her equation has no solution.

her equation could have been
x=x+2

look at it from a common sense point of view.
Can you think of a number which when 2 is added to it would still be the same number???
