#### Answer

All real numbers; identity

#### Work Step by Step

1. Given: 7[2 - (3 + 4x)] - 2x = - 9 + 2(1 - 15x)
2. Apply Distributive Property: 7(2 - 3 - 4x) - 2x = -9 + 2 - 30x
14 - 21 - 28x - 2x = -9 + 2 - 30x
3. Add and subtract:-30x - 7 = -30x - 7
The equation is an identity, so there are an infinite number of solutions (solution set is all real numbers)
