Answer:
2x+3y=240 x+y=100
x=60 cups of lemonade y=40 cups of orange juice
Step-by-step explanation:
First you must create your equations. Everything that has to do with money-- keep in one equation. Everything that has to do with amount--keep in the other equation.
x+y=100 cups
2$x+3$y=$240
Than you simplify the x+y=100 and create an equation that can either be x= or y=. I prefer y= so...I'm going to to that!
y= 100-x then substitute (you can do elimination though) that in for y in the other equation making it 2x+3(100-x)=240 simplify that and make in 2x+300-3x=240 than you must COMBINE LIKE TERMS and than solve which creates a -1x=-60. So x=60! Than you must go into the other equation of x+y=100 cups which and substitute x because you know what that is now! so 60+y=100. So y=40!
