Question

Simplificar:
a) 2 a + [ a – ( a+ b ) ] =

b) 3x – [ x + y – ( 2x + y ) ] =

c) 2m – [ + ( m – n ) – ( m + n ) ] =

a) - [ - 3 a – { b + [ - a + ( 2 a – b ) – ( -a + b ) ] + 3b } + 4 a ] =

e) - [ - ( -a ) ] – [ + ( - a ) ] + { - [ -b + c ] – [ + ( -c ) ] } =

h) - ( a + b ) + ( -a – b ) – ( -b + a ) + ( 3 a + b ) =
