Question

There are 10 less red skittles than orange Skittles in a bag. The orange Skittles are also twice the number of red skittles. Find the number of red and orange Skittles in the bag. In need to write an equation and solve it step by step

Answer 1

Let the number of red skittles be = x

Let the number of orange skittles be = y

Red skittles are 10 less than orange, this gives

x = y-10................(i)

Orange Skittles are twice the number of red skittles, this gives

y = 2x.............(ii)

Incorporating the value of y from second equation into first

x = 2x - 10

hence, x = 10

Now putting the value of x in equation second

y = 2x

y = 2*10

y = 20

Hence, the number of red skittles are 10 and the number of orange skittles are 20.
