Here we will show you how to solve 72x = 55. In other words, we will solve for x in order to find the value of x in this equation:

  72x = 55

The goal is to get x by itself on the left side. First, we divide both sides by 72 like this:

72x       72

=

55       72

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

72x       72

=

55       72

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

x =

55       72

Finally, 55 over 72 is the same as 55 divided by 72. So, we enter that into our calculator to get the final answer:

  x ≈ 0.764
