Answer:
7a+2y
Step-by-step explanation:
Let's simplify step-by-step.
9a−(2y−3a)−(−y−(2y−a))−(2y+4a−3y)
Distribute the Negative Sign:
=9a−(2y−3a)−(−y−(2y−a))+−1(2y+4a−3y)
=9a+−2y+3a+y+2y+−a+−1(2y)+−1(4a)+−1(−3y)
=9a+−2y+3a+y+2y+−a+−2y+−4a+3y
Combine Like Terms:
=9a+−2y+3a+y+2y+−a+−2y+−4a+3y
=(9a+3a+−a+−4a)+(−2y+y+2y+−2y+3y)
=7a+2y
Answer:
= 7a+2y
