Answer:
sum of 5x-4y+6z and -8x+y-2z is -3x-3y-z+6. _eq. (1)
sum of 12xy+3z and -3x+5y-8 is 12xy+3z-3x+5y-8. _eq. (2)
subtract eq. (1) from (2).
=12xy+3z-3x+5y-8 - ( -3x-3y-z+6 )
=12xy+4z+8y-14

Answer:
12xy - z + 8y - 8
Step-by-step explanation:
12xy + 3z - 3x + 5y - 8 - (5x - 4y + 6z - 8x + y - 2z)
= 12xy + 3z - 3x + 5y - 8 - (-3x - 3y + 4z)
= 12xy + 3z - 3x + 5y - 8 + 3x + 3y - 4z
= 12xy - z + 8y - 8
