The sum of two numbers:
x + y = 108
The difference of the same two numbers:
x - y = 78
We can use substitution to figure out x and y:
x - y = 78 can be changed to x = 78 + y
We can plug this into the first equation:
78 + y + y = 108
78 + 2y = 108
2y = 30
y = 15
Now solve for x using any of the two equations. I'll use the first equation since it's easier:
x + 15 = 108
x = 93

Answer:
Step-by-step explanation:
The probability of matching the number drawn on the gold ball is
The number of possible pairs of numbers from 1 to 53 is
Choosing 5 numbers, you are choosing 10 different pairs:
Therefore the probability of correctly matching the drawn pair is
Thus, the probability of winning (matching the pair AND the gold ball) is
