DO NOT forget how to use the distributive property!

1. x/3 = 5/12
    12/12= 5 * 3 = 15/12 = 5/4

2. 3x + 1/5 = x/2
    next you are going to group like terms
    5x= 6x + 2
   -6x   -6x
    5x - 6y = 2
    -1x = 2
    -1    -1
     x = -2 

Tips to remember: 
These two examples are representing and using cross products property
with proportions you can NOT cross simplify
