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.
