A bag contains white marbles and yellow marbles, 16 in total. The number of white marbles is 5 less than 2 times the number of y
bija089 [108]

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.

How do you do ordered pairs
nika2105 [10]
Identify the x-value in the ordered pair and plug it into the equation. When you simplify, if the y-value you get is the same as the y-value in the ordered pair, then that ordered pair is indeed a solution to the equation.
