Answer:
The inequality is true for all x.
[tex](-\infty, \infty) = \mathbb{R}[/tex]
Step-by-step explanation:
[tex]31(2x + 1) - 12x > 50x[/tex]
[tex]62x + 31 - 12x > 50x[/tex]
[tex]50x + 31 > 50x[/tex]
[tex]y+31>y[/tex]
LHS > RHS
Once the LHS will always be greater than RHS for any value of y in the Real Set, the inequality is true for all values of x.
