2a−[4b−4a−(3b−¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯2a+2b)]
=2a−[4b−{4a−(3b−2a−2b)}]
=2a−[4b−4a−(3b−2(a+b))]=2a−[4b−{4a−(3b−2(a+b))}]=2a−[4b−{4a−(3b−2(a+b)}]
=2a−[4b−4a−(3b−2a−2b)]=2a−[4b−{4a−(3b−2a-2b)}]=2a−[4b−{4a−(3b−2a−2b)}]
=2a−[4b−4a−(b−2a)]=2a−[4b−{4a−(b−2a)}]=2a−[4b−{4a−(b−2a)}]
=2a−[4b−4a−b+2a)]=2a−[4b−{4a−b+2a)}]=2a−[4b−{4a−b+2a }]
=2a−[4b−6a−b)]=2a−[4b−{6a−b)}]=2a−[4b−{6a−b}]
=2a−[4b−6a+b]=2a−[4b−6a+b]=2a−[4b−6a+b]
=2a−[5b−6a]=2a−[5b−6a]=2a−[5b−6a]
=2a−5b+6a=2a−5b+6a=2a−5b+6a
=8a−5b=8a−5b=8a−5b
Hence, 2a−[4b−4a−(3b−¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯2a+2b)] =8a−5b
