What is 39482*394830^83949/3848 What is 943948*849349369-33(038480)6When we put 6 in place of x we get:

6 − 2 = 4

which is true

So x = 6 is a solution.

How about other values for x ?

For x=5 we get "5−2=4" which is not true, so x=5 is not a solution.
For x=9 we get "9−2=4" which is not true, so x=9 is not a solution.
etc
In this case x = 6 is the only solution
