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

a). -3m+4n-6-(7n-8m+10)
-3m+4n-6-7n+8m-10
-10m+12n-16
b). 15a+7b-5c-(-11a-12b+13c)
15a+7b-5c+11a+12b-13c
26a+19b-2c

(5x - 6y + 6z) + (7x - 9z) - (2y + 9z + 10)
= 5x + 7x - 6y - 2y + 6z - 9z - 9z + 10
= 12x - 8y - 13z + 10
