Answer:

3a - b - 4c

Step-by-step explanation:

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

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

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

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

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

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

= 2a - 5b + a + 4b - 4c

= 2a + a- 5b + 4b - 4c

= 3a - b - 4c

Thanks
