B. (24, 18)
C. (18, 24)
D. Infinitely many solutions, dependent

Best ResponseYou've already chosen the best response.1Try dividing the second equation by 5 and you can see what will happen. This is a pretty easy problem. You can probably do it by just looking at it.

Best ResponseYou've already chosen the best response.1Ok let me help you. You have two equations, \[4x3y=6\]\[20x15y=30\]Now if you divide the second equation by 5, it means you divide every number by 5, you get:\[\frac{ 20 }{ 5 }x  \frac{ 15 }{ 5}y = \frac{ 30 }{ 5 }\]and the resulting second equation now is:\[4x3x=6\]and it is easy to see that both your first and second equations are the same. If you plot this you can see that they are on top of each other. And just like everything on top of teach other, they touch everywhere therefore you have infinitely many solutions, dependent on an integer n. That is  it depends on you to select a point and you can get the solution for that. Was it easy ;)
