11.
Just look at the graph, and you will see that an original inequality is:
\(x \leq 1\)
Multiply both sides by 5:
\(5x \leq 5\)
Add 6 to both sides:
\(5x+6 \leq 11\)
And you will get an equivalent inequality to \(x \leq 1\).
12.
Just look at the graph, and you will see that an original inequality is:
\(p\ \textgreater \ 2\)
Multiply both sides by 5:
\(5p\ \textgreater \ 10\)
Add 4 to both sides:
\(5p+4\ \textgreater \ 14\)
And you will get an equivalent inequality to \(p\ \textgreater \ 2\).
