Hi,
Let x be the amount of the October bill, then (x-$2.32) would be September's bill
total bill for the two months was $119.56
x + (x-$2.32)= $119.56
Simplify and Solve
2x - $2.32 = $119.56
2x = $121.88
x = $60.94 October's bill
(x-$2.32) = $58.62 September's Bill
check your answer
$60.94 + $58.62 = $119.56
