Answer:
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
<em>Combine like terms</em>
r + b + 6 = 12
<em>Subtract 6</em>
r + b = 6
<em>Because r = b, plug in b for r</em>
b + b = 6
2b = 6
b = 3
Which makes r = 3
That statement is False.
