Answer
$ y\leq -4$.
The graph is shown below.
Work Step by Step
The given inequality is
$\Rightarrow 7+y\leq 3$
Subtract $7$ from each side.
$\Rightarrow 7+y-7\leq 3-7$
Simplify.
$\Rightarrow y\leq -4$
Hence, the solution is $ y\leq -4$.
Use a close circle because $-4$ is a solution.
Shade the number line on the left side.
