Dealing with Fractions & Decimals

Let's start with fractions:
 

Solve  
  		2/7 + 3x = 5

This thing would be a lot easier to solve without this fraction... 
So, let's make that happen!

If we multiply both sides by 7, we'll be able to ditch that fraction!

Check it out:

7 ( 2/7 + 3x ) = 7 ( 5 ) which gives ((7)(2)/7 + 7(3x) = 7(5) which gives a regular equation 2 + 21x = 35 ditch the 2... 2 - 2 + 21x = 35 - 2 which gives 21x = 33 ditch the 21... 21x/21 = 33/21 which gives x = 33/21 = 11/7

I'll let you check it.
