Explanation / Answer

x = number of par 3 holes
y = number of par 4 holes
z = number of par 5 holes

Since total is 18

x+y+z =18

next, total goal is 74, hence

3x+4y+5z= 74

Also

y=2z

Substitute y=2z in both eqaution

x+3z =18

3x+13z =74

hence

x =3, z=5

now

y =2*5 =10

Answer will be

number of par 3 holes= 3
number of par 4 holes= 10
number of par 5 holes=5
