    start by multiplying every term by w will leave 2 + 3w > 29 you should be able to solve it now..

    look at the solution provided by @ktnguyen1 he is saying w is less that 9 pick a value, say w =2 and substitute to check his solution 2/2 + 3 > 29/2 or 4 > 14.5 so the solution is incorrect...

    but he does also have a correct solution in his working... its just the way its written and your solution is correct... to test it pick w = 10 2/10 + 3 > 29/10 3.2 > 2.9 yes... so your solution is correct.
