#color(red)(6b - (5a - 2 [a + (b - 2a)])#

Based on PEMDAS, we solve the innermost parentheses first, and then move outwards

#6b - (5a - 2 [a + b - 2a])#

#6b - (5a - 2 [b - a])#

#6b - (5a - 2b + 2a)#

#6b - (7a - 2b)#

#6b - 7a + 2b#

#8b - 7a #

#color(green)(- 7a + 8b # is the Simplified Form of #color(red)(6b - (5a - 2 [a + (b - 2a)])#
