Answer:
Step-by-step explanation:
Number of marbles with Betty = x
Number of marbles with Adelene = 3x
Adelene gives 25 marbles to Betty.
Now Adelene has (3x - 25) marbles and Betty has (x + 25) marbles.
3x - 25 = x + 25
Add 25 to both sides
3x - 25 +25 = x + 25 + 25
3x = x +50
Subtract x from both sides.
3x - x = x + 50 - x
2x = 50
Divide both sides by 2
2x/2 = 50/2
x = 25
Number of marbles with Betty = 25
Number of marbles with Adelene = 3*25 = 75
Marbles with both = 25 + 75 = 100
It's because if you are only working with positives, then the first quadrant is the only one that can help you, if you draw the other 3, then you just take up too much space to represent something you don't even need to show
