Two inequalities connected with the word "and" tells you that you're looking for the set of x values that satisfies both relations. Your x solution(s) need to make both inequality statements true. On a number line graph, an "and" problem will come together like a dumbell. In a special case, the graph will not come together- rather, they will go out in opposite directions. Since there are no x values that can be in both sets, such problems would have no solution.
