$\huge\boxed{\fcolorbox{black}{violet}{ANSWER..}}$

( 5x + 4y + 7z ) - ( x + 2y + 3z )

= 5x + 4y + 7z - x - 2y - 3z

= ( 5x - x ) + ( 4y - 2y ) + ( 7z - 3z )

= 4x + 2y + 4z

Answer 2

Answer:

-4x-2y-40

Step-by-step explanation:

(x+2y+32) - (5x+4y+72)

as minus is outside the bracket so all the signs are gonna change

x+2y+32-5x-4y-72

now

i solved

x-5x = -4x

2y-4y = -2y

32-72 = -40

i wrote these this way to make u understand how i solved it

so,

answer is

-4x-2y-40
