Let the money that Jane had be x and Ivan had y so they had total of $64.
x + y = $64 ____(1)
❑ After giving Ivan,
⟿ x - 9 = y + 9
⟿ x - y = 9 + 9
⟿ x - y = $18 ____(2)
❑ We've to compare both the Equations (1) and (2) to get desired value as:
x + y = $64
x - y = $18

2x = $82
After Comparing, we found that:
⟿ 2x = $82
⟿ x = $82/2
⟿ x = $41
❑ By Putting value of x in any Equation to get the value of y as to follow :-
⟿ x + y = $64
⟿ $41 + y = $64
⟿ y = $64 - $41
⟿ y = $23
Hence,
$41 of money that Jane have at first.
