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:
|
| = |
|
When a numerator and denominator value are the same, then you can eliminate them by crossing them out:
|
| = |
|
Then you are left with x by itself on the left like this:
| x = |
|
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
