I read the problem as _____*(3.8) = 9*(4) - 9*(_____)
 
Essentially you want the right side to look like the left side. Hence a number *(number).
 
The first step is to use the distributive property.
 
Since you have a 9 in both terms, you can factor the 9 out, so it looks like 9*(4 - ____)
 
You then have ____ * (3.8) = 9*(4 - ____)
 
Does this help you fill in the blanks, or do you need the next steps?
3.8x+9x=9*4=36
12.8x=36
x=36/3.8=9.4736842105263157894736842105263
