Trevor is making two types of bracelets. Each Type P bracelet needs 12 inches of leather and 3 inches of string. Each Type Q bracelet needs 4 inches of leather and 18 inches of string. Trevor has 5 yards of leather and 6 yards of string. x equals the number of Type P bracelets Trevor makes. y equals the number of Type Q bracelets Trevor makes.
