Let x be what she pays for rent. Then she pays 800-x for her car.
So we have:
x = 3*(800-x) - 100
Solve the above for x.

----------------------------------------------
Let her car payment be "x".
--
Then rent is 3x-100
--------------------------
Equation:
x + 3x-100 = 800
4x = 900
x = 225 (car payment)
---
800-225 = 575 (rent payment)
