Answer:
=x2y−2xy2+7y2z
Step-by-step explanation:
Simplify
Let's simplify step-by-step.
4x2y+3y2z−2xy2−3x2y+4y2z
=4x2y+3y2z+−2xy2+−3x2y+4y2z
Combine Like Terms:
=4x2y+3y2z+−2xy2+−3x2y+4y2z
=(4x2y+−3x2y)+(−2xy2)+(3y2z+4y2z)
=x2y+−2xy2+7y2z
Answer:
=x2y−2xy2+7y2z
The number would be 12. If you substitute you will find that 12 is correct.
