There are 13 white marbles in the bag.
Step-by-step explanation:
Given,
Total number of marbles = 24
Let,
x represent the number of white marbles.
y represent the number of yellow marbles.
According to given statement;
x+y=24 Eqn 1
x = 2y-9 Eqn 2
Putting value of x from Eqn 2 in Eqn 1
Dividing both sides by 3
Putting y=11 in Eqn 2
There are 13 white marbles in the bag.
