Answer:
[tex]\Huge \boxed{-15y-9}[/tex]
Step-by-step explanation:
To solve this problem, first you have to use the distributive property of [tex]\displaystyle a(b+c)=ab+ac[/tex].
First, expand.
[tex]\displaystyle -2(5y+6)[/tex]
[tex]-2*5=-10[/tex]
[tex]\displaystyle -2*6=-12[/tex]
[tex]\displaystyle -10y-12[/tex]
[tex]\displaystyle -10y-12+3-5y[/tex]
Next, solve.
[tex]\displaystyle -10-12+3-5=\boxed{-15y-9}[/tex]
In conclusion, the correct answer is -15y-9.
