first represent unknowns using variables:
let x = first decimal
let y = second decimal
then set up equations using conditions given:
(1) x + y = 3.9 (according to first statement)
(2) x - y = 0.9 (according to second statement)
(3) xy = 3.9
i think there's something wrong here because you have more equations than unknowns,, please check your typing.
