Question

How much is 2x + 3y - 8z greater than -2x+7y+9z​

Answer 1

Answer:

2x + 3y - 8z-(-2x+7y+9z)=2x + 3y - 8z+2x-7y-9z

=4x-4y-17z

THEREFORE 2x + 3y - 8z GREATER THAN -2x+7y+9z BY 4x-4y-17z

Answer 2

Answer:

you can subtract from greater one to get the answer

Step-by-step explanation:

(-2x+7y+9z) - (2x+3y-8z)

{remember whenever there is a negative sign before bracket then the numbers that contained by the brackets sign will be flipped.

I mean + will become - &

- will become +}

= -2x +7y+9z-2x+3y-8z

= -4x + 4y + z , is answer
