solve function can't solve an inequality

Hello, i'm trying to solve an inequality with the solve command but it gives me an error that tells me it can't solve my equation. Any alternatives to solve or does someone know how to overcome the error? thanks in advance!

[0 < 320/9 - k/9, 0 < (9*k + (k/9 - 320/9)*(k - 41))/(k/9 - 320/9), 0 < k]
This is the inequality in text form.

I'm able to get a solution with defining k as a real symbolic variable
syms k real
ineqs = [0 < 320/9 - k/9, 0 < (9*k + (k/9 - 320/9)*(k - 41))/(k/9 - 320/9), 0 < k];
A = solve(ineqs, k, 'ReturnConditions', true);
Where A.conditions returns
x < 36*5^(1/2) + 140 & 140 - 36*5^(1/2) < x

Nice find. I will have to remember that work-around for future.
