Hey!
Okay, to solve this problem, we'd first have to multiply both sides by two. The reason we do this is to get

on its own.
Original Equation : 
<
New Equation {Changed by Multiplying 2 on Both Sides} :
<

(

)
And we simplify the equation to get our answer.
Old Equation :
<

(

)
New Equation {Changed by Simplification} :y < -6
So, the equation
< -3 simplified is y < -6.
Hope this helps!
