Answer:
44.
Explanation:
Let, x= white marbles
and y= yellow marbles
Now, according to the first condition
x + y = 58 … (1)
According to the second condition,
x= 3y+2
Or, 3y - x = -2 … (2)
Adding (1) and (2)
4y= 56
Or, y= 14 ... (3)
Now, putting (3) in (1)
x = 44
Therefore there are 44 White marbles and 14 yellow marbles.
