Answer:
9 White marbles are present in the bag.
Step-by-step explanation:
Let the number of White marbles present in the bag be X and number of Yellow marbles present be Y .
Then according to the question ,
X + Y = 16 -(1) (As total marbles are 16)
Also,
X = 2Y - 5 -(2)
From Equation 1 , X = 16 - Y , Comparing with Equation 2 , we get,
16 - Y = 2Y - 5
3Y = 21.
Y = 7.
So, X = 16 - Y = 16 - 7 = 9.
Thus, 9 White marbles are present in the bag.

All you need to do is try the points and see which one makes the inequality TRUE.
(-1,-3) TRUE
-3 ≤ -|-1| -1
-3 ≤ -2
(0,0) FALSE
0 ≤ -|0| - 1
0 ≤ -1
(1,-1) FALSE
-1 ≤ -|1| - 1
-1 ≤ -2
