Answer

6x + 7

Work Step by Step

We write an expression to express this problem: [(4x - 2) + (7x + 6)] - (5x - 3) = Use the distributive property: [4x - 2 + 7x + 6] - 5x + 3 = [11x + 4] - 5x + 3 = Remove square brackets. 11x + 4 - 5x + 3 = Group similar terms. (11x - 5x) + (4 + 3) = Simplify. 6x + 7
