You are correct. You can simply check your answer by plugging in the solution

x-2y%3E6 Start with the first inequality


3-2%28-5%29%3E6 Plug in x=3, y=-5


3%2B10%3E6 Multiply


13%3E6 Add. Since this inequality is true, the solution (3,-5) satisfies the first inequality


x%2B4y%3C-4 Move onto with the second inequality


3%2B4%28-5%29%3C-4 Plug in x=3, y=-5


3-20%3C6 Multiply


-17%3C6 Add. Since this inequality is true, the solution (3,-5) satisfies the second inequality


Since the solution (3,-5) satisfies both of the inequalities, our answer is verified.
