Answer:
4a + 2b + 10c - 11d
Step-by-step explanation:
a + 2b + 3c -7d - (4d - 7c - 3a)
= a + 2b + 3c - 7d - 4d + 7c + 3a
= a + 3a + 2b + 3c + 7c - 7d - 4d
= 4a + 2b + 10c - 11d

a + 2b + 3c - 7d - (4d - 7c - 3a)
= a + 2b + 3c - 7d - 4d + 7c + 3a
= (1 + 3)a + 2b + (3 - 7)c + (-7d)
= 4a + 2b - 4c - 7d
