\({1 \over 2}\) of Danny's money is equal to \( {2\over 3}{}{}\) of Jeff's money. If they have $126

altogether, how much does Jeff have?

Answer = 54
x=Danny's money 

y= Jeff's money

 

x+y126

1/2x-2/3y=0

 

x+y=126

x-4/3y=0

 

7/3y=126

2/3y=36

y=54

 

 

Verification: 54+36x2=126

1/2 d = 2/3 j         d = 4/3 j

 

4/3 j + j = 126

j = 54         then d = 72
