Answer

11x + 6

Work Step by Step

13x - {5x - [4x - (x - 6)]} = Use the distributive property: 13x - {5x - [4x - x + 6]} = Use the distributive property again: 13x - {5x - 4x + x - 6} = Use the distributive property a final time: 13x - 5x + 4x - x + 6 = Group similar terms. (13x - 5x + 4x - x) + 6 = Simplify. 11x + 6
