Question

What is the solution set for 3x+1(more than or equal to)8 and 10x(less than or equal to)15

Answer 1

there is no solution

Answer 2

There is no overlap in the solutions to the two inequalities.

The solution set is the empty set: { }.

_____
The solution to the first is x ≥ (8-1)/3, or x ≥ 2 1/3.
The solution to the second is x ≤ 15/10, or x ≤ 1 1/2.
