There are 10 less red skittles than orange skittles. the orange skittles are also twice the number of ed skittles. find the number of red and orange skittles

red = 10, orange = 20

Step-by-step explanation:

Let R represent the # of red skittles and G represent the # of orange skittles

there are 10 less red skittles than orange skittles: R = G - 10

orange skittles are twice the red skittles: G = 2R

Use substitution to solve the system:

 R = (2R) - 10

-R   -R        

0  = R - 10

+10     +10

10 = R

G = 2R   = 2(10)   = 20
