Problem

Let aa be a real parameter. Solve the inequality (a+2)x−5≥(3a−1)x+4(a+2)x-5 \ge (3a-1)x+4 with respect to xx. (i) Obtain the solution set for xx in terms of aa, clearly distinguishing the cases arising from the sign of the coefficient of xx after simplification. (ii) For which values of aa is the inequality true for every real number xx? Justify your answer. (iii) For which value(s) of aa does the inequality have no solution? Give reasons for your conclusion.
