Answer 1

There are 10 red Skittles and 20 orange Skittles. Hope this helps! :D

Answer 2

There are 10 Red skittles and 20 Orange Skittles

Explanation:

Let's call X the number of red skittles in the bag and Y the number of Orange Skittles in the bag.

If we know that there are 10 less red Skittles than orange Skittles in the bag, we can formulate the following equation:

X = Y - 10

Additionally, we know that the Orange Skittles are twice the number of red Skittles, so we can formulate the following equation:

Y = 2*X

Replacing this last equation on the first and solving for X, we get:

X = Y - 10

X = (2*X) - 10

X + 10 = 2*X

10 = 2*X - X

10 = X

Now, we have the value of X and we can replace this on the equation Y = 2*X and found Y as:

Y = 2*(10) = 20

Then, if X is equal to 10, the number of red skittles in the bag are 10 and Y is equal to 20, so the number of Orange skittles in the bag are 20.
