## frx 2 years ago 98x + 133y = 427 Specify particular the answers (x,y) where x>0 and y>0 I get the answer (-244,183) or the general answer x= 19n-244 y= 183-14n I don't really get the x>0, y>0 part, could anyone guide me through it?

1. mukushla

they want u to find n's for which x and y are positive so u need to solve this inequalities $19n-244>0$$183-14n>0$

2. frx

So the answer should just be where $n >\frac{ 244 }{ 19 }$ or $n <\frac{ 183 }{ 14 }$ Right?

3. mukushla

not or ... it is and...

4. mukushla

thats right ...just note that they are simultaneous

5. frx

So the answer lies within the interval $\frac{ 244 }{ 19}< n < \frac{ 183 }{14}$ ?

6. mukushla

exactly

7. mukushla

just one number satisfies that inequalities :)
