Answer:
circle of diagram (89).&"71
The lines whose equations are given intersect at. (4, 0)
To solve this problem you must apply the proccedure shown below:
1. You have that the number of innings are expressed as a mixed number in the exercise:

2. If you want to write it as a decimal, you can convert the fraction as a decimal by dividing the numerator by the denominator and then, you must add this to the whole number part:

The answer is: 102.67
5x+6y=18
5x=18-6y
x=(18-6y)/5
Use that in the other equation
18(18-6y)/5 - 15y = 36
64.8-21.6y - 15y = 36
28.8=36.6y
.7868=y
Now put that number in for y on the first equation
5x+6(.78) = 18
5x + 4.68 = 18
5x = 13.32
x = 2.66
and y = .78
