Your proportion should look something like this

After cross multiplication, you should end up with this equation

After dividing 4 on both sides, you should get that x=9
 
        
        
        
are you sure you wrote that right?????
 
        
             
        
        
        
8x4=32
32=(yx7)-(yx3)
(yx7)=7y
(yx3)=3y
32=7y-3y
7y and 3y are like terms so you subtract them 
=4y
32=4y
then divided 4y by 4 (to get y on its own) this cancels out if you ÷ 4y on one side of the equation you have to divide on the other side to make it balanced 32÷4=8
y=8
        
             
        
        
        
Answer:
$450
Step-by-step explanation:
The sale price is computed from ...
... sale price = original price - discount
where ...
... discount = (original price) × 26%
Putting these together, we get ...
... sale price = (original price) - 0.26×(original price)
... sale price = (original price) × (1 - 0.26) = 0.74×(original price)
Dividing by 0.74, we find ...
... original price = (sale price)/0.74
... $333/0.74 = $450 = original price
