P=5a+3b-4c+1
Q=3a+5b+3c-8
R=6a-4b-7c+3
(P+Q)-R
(5a+3b-4c+1+3a+5b+3c-8)-(6a-4b-7c+3)
(5a+3a+3b+5b-4c+3c+1-8)-6a+4b+7c-3
(5a+3a-6a+3b+5b+4b-4c+3c+7c+1-8-3)
(2a+12b-6c-10)
2(a+6b-3c-5)
Q=3a+5b+3c-8
R=6a-4b-7c+3
(P+Q)-R
(5a+3b-4c+1+3a+5b+3c-8)-(6a-4b-7c+3)
(5a+3a+3b+5b-4c+3c+1-8)-6a+4b+7c-3
(5a+3a-6a+3b+5b+4b-4c+3c+7c+1-8-3)
(2a+12b-6c-10)
2(a+6b-3c-5)
