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.
the sum of two decimals numbers is 3.9. Their diffrence is 0.9, and their product is 3.9. What are the two numbers
