A bag contains white marbles and yellow marbles 58 in total. The number of white marbles is 2 more than 3 times the number of yellow marbles. How many white marbles are there

44.

Step-by-step 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.
