Question

Is 4x – 3 = 19 true, false, or open?

Answer 1

4x-3=19
4x= 22
x= 22/4 = 6.5

It just means x=6.5 I have no idea if it is true, false or open. To me it simply do not make sense.

A equation like:
x-3= x-2
I can say it is false as (cancel the both x), 3 is not equals to 2.

But for x=6.5 Because of the variable x, it is difficult to ascertain any truth value to it.

Answer 2

open
