a. -3m + 4n - 6 + 7n - 8m + 10
-3m - 8m + 4n + 7n - 6 + 10
= -11m + 11n + 4
b. 15a + 7b - 5c + (-11a) - 12b + 13d
= 15a - 11a + 7b - 12b - 5c + 13d
= 4a - 5b - 5c + 13d
2.
a. 7n - 8m + 10 - (-3m) + 4n - 6
= 7n - 4n - 8m + 3m + 10 + 6
= 3n - 5m + 16
b. -11a - 12b + 13d - 15a + 7b -5c
= -11a - 15a - 12b + 7b + 5c + 13d
= -26a - 5b + 5c + 13d
Semoga membantu :)
