X= 48 is the correct answer. You can always plug in 48 back into the original equation and make sure it works.
48-23+84+48+23=180
The formula for density is:
Mass/Volume, or in other terms, mass divided by volume.
So, lets look at our numbers:
We know our mass is 84 grams, and our volume is 12 cc. So, all we need to do is divide 84 by 12, which is 7.
So, the density is 7.
