3(2x - 4) - 4x < 2x + 3
6x - 12 - 4x < 2x + 3
2x - 12 < 2x + 3
-12 < 3
The resulting statement is true without the need of any value of x. Therefore, any value for x would solve this equation.

so:
6x - 12 < 2x + 3
4x < 15
x < 15/4
depends on where do you resolve that inequality. if it's in R => Solution = ( infinite sign - that weird "8" , 15/4 )
if it's in N => S = {..., 3}

Nice try. What does the book say and why do you think it is wrong?
