Ah, ok

remember, a(b+c)=ab+ac

order of operations so combine inside parntaheses first
all inside parnthaeses are simlfied

now distribute
7(x-3)=7(x)+7(-3)=7x-21

other distribute
-2(7+4x)=-2(7)-2(4x)=-14-8x

so we have

9x-5+7x-21-14-8x-3x
group like terms
9x+7x-8x-3x-5-21-14
add like terms
5x-40
