Answer 2

Step-by-step explanation:

You need to isolate the variable to solve for x.

So, in order to get rid of the 2, we have to divide by 2 on both sides, so that the equation stays the same.

So, 2x divided by 2 equals x.

5 divided by 2 equals 2.5.

The ending equation is x = 2.5

So, x is 2.5
