Answer:Distribute the coefficients inside the parentheses: [2(x+4) - 3[3x + 2(4-9x)]]
Distributing the 2: [2x + 8 - 3[3x + 2(4-9x)]]
Distributing the 3: [2x + 8 - 9x - 6(4-9x)]
Distribute the 6 inside the second set of brackets: [2x + 8 - 9x - 24 + 54x]
Combine like terms: [2x - 9x + 54x + 8 - 24]
[47x - 16]
Therefore, the simplified expression is 47x - 16.
