Twelve marbles are in a
row. One third of them are yellow. There are an
equal amount of red and blue. There are two less
green marbles than yellow. Explain how to find out
how many of each color of marble are in the row. pls answer I'll make brainliest! and due tomorrow. also please explain

yellow = 4

green = 2

blue = 3

red = 3

Explanation:

y = yellow marbles

r = red marbles

b = blue marbles

g = green marbles

y + r + b + g = 12

y = 1/3 (12) = 4

r = b

g = y - 2 = 4 - 2 = 2

That means...

4 + r + b + 2 = 12

Combine like terms

r + b + 6 = 12

Subtract 6

r + b = 6

Because r = b, plug in b for r

b + b = 6

2b = 6

b = 3

Which makes r = 3
