Answer:
Ryan has 206 model cars.
Step-by-step explanation:
This can be represented in the equations below, where b is amount of cars Barney has and R is amount of cars Ryan has.
![b = 103 \\ r = 2b](https://tex.z-dn.net/?f=b%20%3D%20103%20%5C%5C%20r%20%3D%202b)
If we insert b (which is 103) in for b in the second equation, you'd find the answer.
![r = 2(103) \\ r = 206](https://tex.z-dn.net/?f=r%20%3D%202%28103%29%20%5C%5C%20r%20%3D%20206)
