Question

Simplify: (4x – 3y + z ) – (12x + 8y – 2z) + (x + y – z)

Answer 1

Answer:

2z-10y-7x

Step-by-step explanation:

= ( 4 x - 3 y + z ) - ( 12 x + 8 y - 2 z ) + ( x + y - z )

= 4x-3y+z-12x-8y-\left(-2z\right)+x+y-z

= 4x-3y+z-12x-8y+2z+x+y-z

= -8x-3y+z-8y+2z+x+y-z

= -8x-11y+z+2z+x+y-z

= -8x-11y+3z+x+y-z

= -7x-11y+3z+y-z

= -7x-10y+3z-z

= -7x-10y+2z

= 2z-10y-7x
