Here we will show you how to solve 7x = 31. In other words, we will solve for x in order to find the value of x in this equation:
7x = 31
The goal is to get x by itself on the left side. First, we divide both sides by 7 like this:
7x
7
=
31
7
When a numerator and denominator value are the same, then you can eliminate them by crossing them out:
7x
7
=
31
7
Then you are left with x by itself on the left like this:
x =
31
7
Finally, 31 over 7 is the same as 31 divided by 7. So, we enter that into our calculator to get the final answer:
x ≈ 4.429
