How do you solve 9- 4( 2x + 5) = - 11?

$x = 0$

Explanation:

We can start by distributing the $- 4$ to the terms in the parenthesis. Here, we are just multiplying. We get:

$9 - 8 x - 20 = - 11$

We can combine the like terms on the left to get:

$- 11 - 8 x = - 11$

The $- 11$s on both sides will cancel, resulting in zero, so we're left with $- 8 x = 0$, which will obviously evaluate to $x = 0$.
