For this case we must resolve the following inequality:


-2 (w + 4) +9 <-11

We apply distributive property to the terms within parentheses:


-2w-8 + 9 <-11

We add similar terms from the left side of the equation:


-2w + 1 <-11

We subtract 1 from both sides of the inequality:


-2w <-11-1\\-2w <-12

We divide between -2 on both sides taking into account that the sense of inequality changes:


w> \frac {-12} {- 2}\\w> 6

Answer:


w> 6
