G135 B (11) (a-10)+(5a-2)= (12) (a-10)-(5a-2)= (13) (a-10)+(-5a-2)= (14) (a-10)-(-5a-2)= (15) (a-2b+3c)+(-2a+b)= (16)

Question

G135 b (11) (a-10)+(5a-2)= (12) (a-10)-(5a-2)= (13) (a-10)+(-5a-2)= (14) (a-10)-(-5a-2)= (15) (a-2b+3c)+(-2a+b)= (16) (a-2b+3c)-(-2a+b)= (17) (a-2b+3c)+(3b+a)= (18) (a-2b+3c)-(3b+a)= (19) (a-2b+3c)+(-2a+3c)= (20) (a-2b+3c)-(-2a+3c)=
