3(5y + 6) - 4

First, distribute so that it will make the solving easier.
\((3)(5y) + (3)(6) - 4\)
Second, since parentheses indicate multiplication, '3 × 5y = 15y'.
\(15y + (3)(6) - 4\)
Third, multiply '3 × 6' to get '18'.
\(15y + 18 - 4\)
Fourth, subtract '18 - 4' to get '14'.
\(15y + 14\)

Answer: C)  15y + 14
