How do i solve this 9x-5+7 (x-3) - 2 (7+4x) - 3x

distributive property and combining like terms pre algebra

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
