You can put this solution on YOUR website! x/4 is < than or = to 5.9
(x/4)=<(5.9)
Multiplying by 4 which is >0 (multiplying by a positive quantity does not alter the inequality and so here less than will remain less than itself and of course equality remains)
x =< 4X(5.9)
x =< 23.6
Answer: x =< 23.6
Verification : satisfies orally itself can be very well seen!
