Answer:
  x=0 and y=2
Step-by-step explanation:
We have been given system of equations:
2x+5y=10     (1)
And 2x+3y=6     (2)
Subtract equation (2) from(1) we get:
2y=4
y=2
Now, substitute y=2 in equation(2) we get:
2x+3(2)=6
2x+6=6
2x=0
x=0
Hence, x=0 and y=2
 
        
             
        
        
        
Answer:
-46.91%
Step-by-step explanation:
Given:
Cost of buying the shares = $53,500
Selling cost of the shares = $3,300
Number of years = 2
Since the selling cost is less than the buying cost, therefore the statement for the loss can be verified
Now, 
The loss = Selling cost - cost of buying = $3,300 - $53,500 = - $50,200
thus, the loss per year =  = -$25100
 = -$25100
Hence, 
Rate of return = 
or
Rate of return = 
or
Rate of return = -46.91%
 
        
             
        
        
        
7720 + 80x = 3200 + 120x
I think this is correct.  Hope it helps!
