Answer

-16x + 3

Work Step by Step

-10x - {7x - [3x - (2x - 3)]} = Use the distributive property: -10x - {7x - [3x - 2x + 3]} = Use the distributive property again: -10x - {7x - 3x + 2x - 3} = Use the distributive property a final time: -10x - 7x + 3x - 2x + 3 = Group similar terms. (-10x - 7x + 3x - 2x) + 3 = Simplify. -16x + 3
