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