Question

only no. 6 pls answer!​

Answer 1

Answer:

7a - 4b - [ 5a - 3a{ b- 2(a - b)}]

7a - 4b - [5a - 3a{ b- 2a + 2b}]

7a - 4b - [ 5a - 3a{- 2a + 3b}]

7a - 4b - [ 2a { -2a + 3b}]

7a - 4b - [ -4a^+ 5ab]

7a - 4b + 4a^ - 5ab

_________________________

→ 7a - 4b - [ 5a - 3 { b - 2 (a - b)}]

→ 7a - 4b - [ 5a - 3 { b - 2a + 2b }]

→ 7a - 4b - [ 5a - 3 { 3b - 2a }]

→ 7a - 4b - [ 5a - 9b + 6a ]

→ 7a - 4b - [ 11a - 9b ]

→ 7a - 4b - 11a + 9b

→ 5b - 4a
