Its 2.25x + 1.5x > -307 <=>

<=> 3.75x > -307 <=> 

<=> x>- 307/3.75 or x> -81.8666...

I hope to help you!

I think I will try it too. :)

 

\(2.25x>-1.5x-(250+57)\\ 2.25x>-1.5x-307\\ 2.25x{\color{red}{+1.5x}}>-1.5x{\color{red}+1.5x}-307\\ 3.75x>-307\\ x>-307\div 3.75\\ x>-81\frac{13}{15} \)

 

 

There you go, we both got the same answer. :))
