Green = g
Blue = b
Red = r
g+b = 1500
g+r = 750
g+b+r = 2000
in the 1st equation solve for b
g+b =1500
b = 1500-g
2nd equation solve for r
g+ r = 750
r = 750-g
now substitute the answers fro. b and r into the final equation.
g+b+r = 2000
g + 1500-g + 750-g = 2000
-g + 2250 = 2000
-g = -250
g = 250
So we k own the green bike is $250.
Blue = 1500- g
blue = 1500-250= $1250
red = 750-g
red = 750-250 = $500

Step-by-step explanation:
Answer:
C
Step-by-step explanation:
If you multiply the top equation by 2 and the bottom equation by -5, then there will be a 10x in the first equation and a -10x in the second, which you can cancel out in the next step. Therefore, the correct answer choice is C. Hope this helps!
