Step 1. Add 70 to both sides
[tex]-np\ \textless \ 40+70[/tex]
Step 2. Simplify 40 + 70 to 110
[tex]-np\ \textless \ 110[/tex]
Step 3. Divide both sides by [tex]p[/tex]
[tex]-n\ \textless \ \frac{110}{p} [/tex]
Step 4. Multiply both sides by [tex]-1[/tex]
[tex]n\ \textgreater \ - \frac{110}{p} [/tex]
Done! :)
