1) 3b+(5a-7b) = 3b+5a-7b = -4b+5a
2) -3q-(8p-3q) = -3q-8p+3q = -8p
3) 5x+(11-7x) = 5x+11-7x = -2x+11
4) -(8c-4)+4 = -8c+4+4 = -8c+8
5) (2+3a)+(7a-2) = 2+3a+7a-2 = 10a
6) -(11a+b)-(12a-3b) = -11a-b-12a+3b = -23a+2b
7) (5-3b)+(3b-11) = 5-3b+3b-11 = -6
8) (5a-3b)-(2+5a-3b) = 5a-3b-2-5a+3b = -2
9) a+(a-10)-(12+a) = a+a-10-12-a = a-22
10) (6x-8)-5x-(4-9x) = 6x-8-5x-4+9x = 10x-12
11) (1-9y)-(22y-4)-5 = 1-9y-22y+4-5 = -31y
12) 5b-(6b+a)-(a-6b) = 5b-6b-a-a+6b = 5b-2a
