Answer:
y = 
Step-by-step explanation:
Given
Ry - wy = t ← factor out y from each term on the left side
y(R - w) = t ( divide both sides by (R - w ) )
y = 
 
        
                    
             
        
        
        
Lets Anna's age = A
Mr. Goldstein age = G
Mr. Goldstein is 4 times as old as his daughter Anna.
So G= 4A
 In 4 years, he will be 3 times as old as Anna 
we add 4 with Both their ages
G + 4  = three times of A + 4 
G + 4= 3(A + 4)
We know G= 4A, replace it in above equation
4A + 4= 3(A + 4)
4A + 4= 3A + 12
Subtract 3A from both sides
A + 4 = 12
Subtract 4 from both sides
A = 8
So Anna's age = 8 years
 
        
             
        
        
        
-2x + 12 = 2y
Add 2x on both sides,
12 = 2y + 2x
Divide by 2 on both sides,
6 = y + x -> x + y = 6
The answer is D.
