Let the number be y,
From the question, the equation can be written thus;
[tex]3y+4>22[/tex]The next step is to subtract 4 from both sides;
[tex]\begin{gathered} 3y>22-4 \\ 3y>18 \end{gathered}[/tex]We'll then have to divide both sides by 3;
[tex]\begin{gathered} \frac{3y}{3}>\frac{18}{3} \\ y>6 \end{gathered}[/tex]
