Answer 2

Answer:

10x—7y—2z

Step-by-step explanation:

3x—(4y—7x+3y)—2z

= 3x—4y+7x—3y—2z

= (3x+7x) — (—4y—3y) — (2z)

= 10x — 7y — 2z

= 10x—7y—2z Ans

$3x - (4y - 7x + 3y) - 2z \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \\ = (3x + 7x) - ( - 4y - 3y) - (2z)\\ = 3x - 4y + 7x - 3y - 2z \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \\ = 10x - 7y - 2z \: \: \: \: \: ans \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \:$
