Question

subtract 3x-4y-7z from the sum of x-3y+2z and -4x+9y-11z

Answer 1

Answer:

Hey friend,

Here is the answer you are searching for,

Sum of x-3y+2z and -4x+9y-11z

= (x-3y+2z)+(-4x+9y-11z)

= x-3y+2z-4x+9y-11z

= -3x+6y-9z

Therefore,

Required answer

= (-3x+6y-9z)-(3x-4y-7z)

= -3x+6y-9z-3x+4y+7z

= -6x+10y-2z

HOPE IT HELPS YOU.

Answer 2

Answer:

= (-7x +16y - 2z)

Step-by-step explanation:

={(3y+2z) + (-4x+9y-11z)} - (3x- 4y-7z)

={3y+2z-4x+9y -11z} - (3x-4y-7z)

={12y-9z-4x} - (3x-4y-7z)

=12y-9z-4x-3x -(-4y) -(-7z)

=12y -9z-7x+4y +7z

= -7x +12y +4y -9z+ 7z

=-7x +16y - 2z
