A invests x amount of money.
B invests mx;
C invests mx+x;
D invests (mx)+(mx+x)=2mx+x.

The sum of their investments is stated as s dollars.
Solve this for x but it will be IN TERMS OF s.

The solution of this problem is same as Vicenta did above. I think you need to do practice algebraic question and keep in mind algebraic formulas to solve such questions in future. May and other math related website help to do good practice and help to understand formulas with the help of examples.
