Answer
$y=-9$.
Work Step by Step
The given equation is
$\Rightarrow 3y+11=-16$
Subtract $11$ from each side.
$\Rightarrow 3y+11-11=-16-11$
Simplify.
$\Rightarrow 3y=-27$
Divide each side by $3$.
$\Rightarrow \frac{3y}{3}=\frac{-27}{3}$
Simplify.
$\Rightarrow y=-9$
Check:-
$\Rightarrow 3(-9)+11=-16$
$\Rightarrow -27+11=-16$
$\Rightarrow -16=-16$
True.
Hence, the solution is $y=-9$.
