Answer 2

Answer:

Larger number = 39

Smaller number = 27

Step-by-step explanation:

x +  y = 66

x - y =   12                Add

2x = 78                    Divide by 2

2x/2 = 78/2

x = 39

x + y = 66               Substitute for x  

39 + y = 66            Subtract 39 from both sides.

39-39+y=66-39     Combine

y = 27
