Patient A received 150 "milligrams", while Patient B received 50 "milligrams".

Explanation:

This is a system of linear equations; write a system that satisfies this.

Let's say Patient A is x and Patient B is y.

overbrace"3 times the amount of certain medicine as Patient B."^(3y=x)

overbrace"The two doses add to 200 milligrams."^(x+y=200)

Substitute:

3y=x

x+y=200

--------

3y+y=200

4y=200

y=50

Plug in y to solve for x:

50+x=200

x=150

Patient A received 150 "milligrams", while Patient B received 50 "milligrams".
