The simplified result is $- 7 x - 9$ $-7x-9$ , details are below...

The number to the left of the bracket must be looked at as (-3) rather than subtraction of 3.

When you do the multiplication, you multiply $4 x$ $4x$ and $5$ $5$ both by $- 3$ $-3$

$(- 3) (4 x) + (- 3) (3) + 5 x$ $(-3)(4x) + (-3)(3) + 5x$

$- 12 x - 9 + 5 X$ $-12x -9 +5X$

$- 7 x - 9$ $-7x-9$
