To determine which values are solutions we need to solve the inequality:
[tex]\begin{gathered} 13+3r>7 \\ 3r>7-13 \\ 3r>-6 \\ r>-\frac{6}{3} \\ r>-2 \end{gathered}[/tex]
this means that the values that are solutions to the inequlity have to be more than -2.
From the list we conclude that the values that are solutions are: 2, 0, 3 and 5. The other values given are not solutions.
