Question

Any has 6 more blue feathers than white. She has 2 more green feathers than blue feathers. Amy has 4 white feathers. How many green feathers does Amy have?

Answer 1

b = w + 6
g = b + 2
w = 4

b = w + 6
b = 4 + 6
b = 10 <== 10 blue feathers

g = b + 2
g = 10 + 2
g = 12 <== 12 green feathers
