4y - 9 = 3
add 9 to both sides
4y = 12 
divide both sides by 4 so 4 divided by 4 is one and 12 divided by 4 is 3 thus getting your answer of 3
y=3
        
             
        
        
        
Y=(1)/(3)x-9 that’s the answer
        
             
        
        
        
Answer:
25
Step-by-step explanation:
Well, we need to simplify this. we have a ratio of 80:125.
As these numbers end in either 0 or 5, we know they are divisible by 5.
By dividing these by five, our ratio becomes 16:25.
As we have 16 jackets, we know we must need to sell 25 jackets to maintain the ratio.

Step-by-step explanation:
you should only make one equation:
75 + 45x = 30 + 55x
subtract the 30 frim both sides, then subtract 45x from both sides. you are left with:
45 = 10x
Divide by 10 and get:
4.5 = x
