Dear sudha

5x+5-x has minimum value of 2 because we know that x+1/x has min value 2 if x is positive

You can get this by using (x - 1/x)2 > 0

sinx max value is 1

so there cant be any solutions

Please feel free to post as many doubts on our discussion forum as you can.we will get you the answer and detailed  solution very  quickly.

All the best.
