34.5=32+[(53-a)\(106-a-b)]9
34.5-32=477-9a\106-a-b
2.5=477-9a\106-a-b
477-9a=2.5(106-a-b)
477-9a=265-2.5a-2.5b
477-265-9a+2.5a=-2.5b
212-7.5a=-2.5b
-7.5a+2.5b+212=0
-(7.5a-2.5b-212)=0
7.5a-2.5b-212=0
34.5-32=477-9a\106-a-b
2.5=477-9a\106-a-b
477-9a=2.5(106-a-b)
477-9a=265-2.5a-2.5b
477-265-9a+2.5a=-2.5b
212-7.5a=-2.5b
-7.5a+2.5b+212=0
-(7.5a-2.5b-212)=0
7.5a-2.5b-212=0
