I need the inequility of 2.25x>-1.5x-(250+57). All that I know about it is that the aswer is not x>147.
Its 2.25x + 1.5x > -307 <=>
<=> 3.75x > -307 <=>
<=> x>- 307/3.75 or x> -81.8666...
I hope to help you!
Thanks Dimitristhym and welcome to our web2.0calc forum
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. :))
