Answer

2a +4b -2c

step by step explanation

a -2b- [4a -6b -{3a -c - (3a -2b -5a -c -2b)}]

a -2b -[4a -6b -{3a -c - (3a -2b -5a +c +2b)}]

a -2b -[4a -6b -{3a -c -(3a -5a -2b +2b +c)}]

a -2b -[4a -6b -{3a -c -(-2a +c )}]

a -2b -[4a -6b -{3a -c +2a -c }]

a -2b -[4a -6b -{3a + 2a -c -c }]

a -2b -[4a -6b -{5a -2c}]

a -2b -[4a -6b -5a +2c ]

a -2b -[4a -5a -6b +2c]

a -2b -[-a -6b +2c]

a -2b +a +6b -2c

a +a -2b +6b -2c

2a +4b -2c

Answer 2

Step-by-step explanation:

a - 2b - [ 4a - 6b -{ 3a - c -( 3a - 2b - 5a - c - 2b)}]

a - 2b - [4a - 6b - {3a - c - 3a + 2b + 5a + c + 2b}]

a - 2b - [4a - 6b - 3a + c + 3a - 2b - 5a - c - 2b]

a - 2b - 4a + 6b + 3a - c - 3a + 2b + 5a + c + 2b

2a +6b
