Answer:
<u>(a):  9x + 45</u>
Option A, 9(x + 5) because it distributes into 9x + 45
Option B, 9 * x + 9 * 5 because it multiplies into 9x + 45
<u>(b):  13 + 9y - 3 - y</u>
Option D, 8y + 10 because it combines into this number
 
        
             
        
        
        
4x - 1/3 = 7/1 
      +1/3    +1/3 
_______________
4x = 7.3 (repeating) 
(divide each side by 4)
x = 7.3 (repeating) / 4
