-At the end of the 2000 baseball season, the New York Yankees and the Cincinnati Reds had won a total of 31 World Series. The Yankees had won 5.2 times as many World Series as the Reds. How many World Series did each team win?

Step by step please

1 answer

Let's define:
x = number of World Series won by the Cincinnati Reds
y = number of World Series won by the New York Yankees

We can create a system of equations based on the given information:
1) x + y = 31 (The total number of World Series won by both teams is 31)
2) y = 5.2x (The Yankees won 5.2 times as many World Series as the Reds)

To solve this system of equations, we can use the substitution method. Let's solve equation (2) for y:

y = 5.2x

Now substitute this expression for y in equation (1):

x + 5.2x = 31

Combine like terms:

6.2x = 31

Divide both sides by 6.2:

x = 31/6.2
x = 5

So the Cincinnati Reds won 5 World Series.

Now substitute this value of x into equation (2) to find y:

y = 5.2x
y = 5.2 * 5
y = 26

Therefore, the New York Yankees won 26 World Series.
