Answer:
b
Step-by-step explanation:
Each box represents 1/3. 5/3 of white is 2 boxes more so red needs 2 boxes more than white. 5 red and 3 white is the only one that follows the criteria.
First, multiply the top equation by 2 and bottom by -3.
60x+60y=900
-60x-75y=-1035
————————
-15y=-135
—————-
-15=-15
y=9
So the answer should be 9.

Answer:
x=2, y=-2
(2, -2)
Step-by-step explanation:
x + y = 0
3x - 2y = 10
3x - 2(0 - x) = 10 ( 2(0 - x) = -2x )
3x - (-2x) = 10 ( y = -x )
3x + 2x = 10
5x = 10
x = 2
