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
