Answer

-x - 11

Work Step by Step

We write an expression to express this problem: [(9x - 4) + (-3x - 2)] - (7x + 5) = Use the distributive property: [9x - 4 -3x - 2] - 7x - 5 = Remove square brackets. 9x - 4 -3x - 2 - 7x - 5 = Group similar terms. (9x - 3x - 7x) + (-4 - 2 - 5) = Simplify. -x - 11
