Enam lima seper tuju kurang satu satu seper dua sama dengan

You don't say how many numbers you want to do that with.
If you want just two numbers, then they're +7.3107 and -12.3107 . (Those are rounded, not exact.)
I took a quick look among the factors of 90, looking for sets of 3 numbers
that would do it, and I couldn't find any.

let x-------> the first number y-------> the second number
we know that
x + y = − 5 x = − 5 − y equation 1
x ∗ y = − 90 equation 2
substitute the equation 1 in equation 2
[ − 5 − y ] ∗ y = − 90 − 5 y − y 2 = − 90 y 2 + 5 y − 90 = 0
using a graphical tool to resolve the second order equation see the attached figure the numbers are -12.311 7.311

The two numbers that add up to -5 and multiply to -90 are approximately -12.31 and 7.31. To find these numbers, we set up a system of equations based on the addition and multiplication conditions. By solving the resulting quadratic equation, we found the solutions for both numbers.
