x = amt to Xu

4x = amt to Adrian

3(x + 50) = amt to Vicky

2x -100  = amt to Cynthia

5 ( x + 4x)  =  amt to Franklin

4(2x - 100)  =  amt to Vivien

 

x  + 4x  + 3(x + 50) +  (2x - 100) + 5(x + 4x) + 4(2x - 100)  = 3950   simplify

 

5x + 3x + 150 + 2x - 100 + 5x  +  20x  + 8x - 400  = 3950

 

43x  -350   = 3950     add 350 to both sides

 

43x  = 4300   divide both sides by  43

 

x  = 100  =   amt to Xu

4(100)=  400 = amt to Adrian 

3(100 + 50) = 450 = amt to Vicky

2(100) - 100 = 100 = amt to Cynthia

5(100 + 4(100) ) = 2500 = amt to Franklin

4 ( 2(100) -100) =  400 = amt to Vivien
