Answer

No solution.

Work Step by Step

Using the test point \[\left( 0,0 \right)\] for each inequality. \[3x+y<9\], includes origin. \[3x+y>9\], doesn’t include origin. The line \[3x+y=9\] is not included in both inequalities, it is a dashed line. Since, there is no intersection between the inequalities, there is no solution.
