Answer:

312a + 102b - 468

Explanation:

1) First solve the parenthesis.

9 [ 7(3a + 2b - 4) + 12(a - 2) ] + 3(5a - 8b)

9 [ 21a + 14b - 28 + 12a - 24) ] + 15a - 24b

2) Combine like terms.

9 [ 33a + 14b - 52) ] + 15a - 24b

3) Solve the bracket.

297a + 126b - 468 + 15a - 24b

4) Combine like terms.

312a + 102b - 468
