Solve 3x = 18


Here we will show you how to solve 3x = 18. In other words, we will solve for x in order to find the value of x in this equation:

  3x = 18

The goal is to get x by itself on the left side. First, we divide both sides by 3 like this:

   
3x
 
   
3
 
  =
   
18
 
   
3
 

When a numerator and denominator value are the same, then you can eliminate them by crossing them out:

   
3x
 
   
3
 
  =
   
18
 
   
3
 

Then you are left with x by itself on the left like this:

   x =
   
18
 
   
3
 

Finally, 18 over 3 is the same as 18 divided by 3. So, we enter that into our calculator to get the final answer:

  x = 6
