1) 5a+(-8b)+(-7c)+(-2a)+3b+c
2)3n+6m+(-15k)+(-n)+(-5m)+8k
3)8,2a+(-4b)+10,3c+(-4a)+(-9,5b)+(-8c)
1) 5а - 8b - 7c - 2a + 3b + c
3a - 5b - 6c
2) 3n + 6m - 15k - n - 5m + 8k
2n + m - 7k
3) 8,2a - 4b + 10,3c - 4a - 9,5b - 8c
4,2a - 13,5b + 2,3c
1) 5a-8b-7c-2a+3b+c = 3a-5b-6c
2) 3n+6m-15k-n-5m+8k = 2n+m-7k
3) 8.2a-4b+10.3c-4a-9.5b-8c = 4.2a-13.5b+2.3c
