 = 
To find equivalent fractions, multiply be any number that is the same for the numerator/denominator
You can also divide, but it must be divisible by both the numerator/denominator
 
        
             
        
        
        
Answer:
Add 4 on both sides.
In the equation there is a -4. 
If -4+4=0, that is how you would get rid of the -4.
But, you need to add 4 to 29 to really get rid of the -4.
So, 29+4 is 33.
b=33
