[tex]6y + 3 \ \textgreater \ - 18 x[/tex]
Subtract 3 from both sides:
[tex]6 y + 3 - 3 \ \textgreater \ - 18 x - 3[/tex]
[tex]6y \ \textgreater \ - 18 x - 3[/tex]
Dividade both sides by 6 :
[tex] \frac{6y}{6} \ \textgreater \ \frac{-18x-3}{6} [/tex]
[tex]y \ \textgreater \ \frac{-18x-3}{6} [/tex]
hope this helps!
