Remember, you can do anything to an equiton as long as you do it to both sides

-(7-4x)=9
we can either distribute to get -7+4x=9 or multiply both sides by -1 to get
7-4x=-9
then minus 7 both sides
-4x=-16
divide by -4 both sides
x=4

Plug in a value for p and q to figure this out.

(x+4)(x+5)
x^2+5x+4x+20
x^2+9x+20

Here, the coefficient for the x term is 9 and 9 is the sum of p and q (4+5).
