Answer: 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
