    It looks like you shaded the wrong part, if you shade the part you didn't shade then you'd be right

    Hello, andyboy179!

    \text}I need to shade this region: }\;\begin{Bmatrix} y \:<\: 3x-1 \\ y \:<\: 3 \\ x \:<\: 5 \end{Bmatrix}

    You have shaded the wrong side of each inequality.


    Graph the lines: . \begin{Bmatrix}y \:=\:3x-1 \\ y \:=\:3 \\ x \:=\:5 \end{Bmatrix}

    Then shade the region below or to the left of the lines.


    Code:
            |
            |        /
            |       *
            |      /|
            |     / |
           3|    /  |
        - - * - / - + - -
            |  /:::::
            | /:::::|
            |/::::::|
      ------*:-:-:-:*-----
           /|:::::::|5
          /:|:::::::|
         /::|:::::::|
            |

    The final region is the area that has been shaded three times.
