Answer

All real numbers; identity

Work Step by Step

1. Given: 4[6 - (1 + 2x)] + 10x = 2(10 - 3x) + 8x 2. Apply Distributive Property: 4(6 - 1 - 2x) + 10x = 20 - 6x + 8x 24 - 4 - 8x + 10x = 20 - 6x + 8x 3. Add and subtract: 2x + 20 = 2x + 20 The equation is an identity, so there are an infinite number of solutions (the solution set is all real numbers).
