Find the number of par-3, par-4 and par-5 holes respectively

Answer to Problem 52RE
Number of par-3 holes is 2
Number of par-4 holes is 14
Number of par-5 holes is 2
Explanation of Solution
Given:
Total numbers of holes on course is 18.
Let x, y, z be the number of par-3, par-4, and par-5 holes respectively
Total holes is 18; therefore
And given that
Consider the system of equations
Substitute (2) in (1) for z
Substitute -5 for z and -4 for y
Subtracting (4) from (3),
Substitute
Substitute
Hence, number of par-3 holes is 2
Number of par-4 holes is 14
Number of par-5 holes is 2
