Answer:

12 marbles per bag

Step-by-step explanation:

Your equation would be 3x=x+24 because you have 3 bags of marbles with x number of marbles per bag, and your friend has 1 bag with x marbles plus 2 additional marbles

Then you solve this equation

3x=x+24

Subtract x from both sides

2x=24

divide both sides by 2

x=12
