Perform operations to each side of the equation to isolate xx and find that
x = 2x=2

Explanation:

Performing operations like addition and division to each side of an equation maintains the validity of the equality. We use these in a particular order to isolate xx.

First, we use addition to isolate the term containing xx.

3x - 5 = 13x−5=1

=> 3x - 5 + 5 = 1 + 5⇒3x−5+5=1+5

=> 3x = 6⇒3x=6

Now, we use division to remove the coefficient from the xx term.

=> (3x)/3 = 6/3⇒3x3=63

=> x = 2⇒x=2
