Answer:
Wilton found 10 dimes while cleaning his father's truck.
Step-by-step explanation:
Given that:
Total amount collected = $8.50 = 8.50*100 = 850 cents 
Let, 
x be the number of dimes
y be the number of quarters 
According to given statement,
10x+25y=850     Eqn 1
y = 3x     Eqn 2 
Putting y=3x in Eqn 1

Dividing both sides by 85

As x represents dimes, therefore, number of dimes is 10.
Hence, 
Wilton found 10 dimes while cleaning his father's truck.
 
        
             
        
        
        
It would be y=4x-2 because:
8x-3y=6-4x
-8x         -8x
-3y=6-12x
/-3  /-3 /-3
y=-2+4x
y=4x-2
