The ratio of horseshoes to shamrocks was 11 to 5, and two times the number of shamrocks was 12 less than the number of horseshoes. How many were shamrocks?
thank you :)

Math ratio word problem 
bobpursley,
Rachal, I messed that up.
H/S=11/5 so 5H=11S
and 2S+12=H
From the first equation H=11S/5
putting that into the second.
2S+12=11S/5
multiplying both sides by 5
10S+60=11S
adding sixty to both sides and subtracting 11S from both sides.
S=60 or S=60
so H=11*60/5=132
