How do you solve $2 [x + 5 (2 x + 4) - 8] = - (x + 9)$ $2[x+5(2x+4) -8] = -(x+9)$ ?

$x = - \frac{33}{23}$ $x=-33/23$

Explanation:

By expanding we get

$2 (x - 8 + 10 x + 20) = - x - 9$ $2(x-8+10x+20)=-x-9$

$22 x + 24 = - x - 9$ $22x+24=-x-9$
$23 x = - 33$ $23x=-33$
$x = - \frac{33}{23}$ $x=-33/23$
