Let's mark a number with x.
Product of that number and -15 is P1.

Product of that same number and 9 is P2.

It says that P1 decreased by 25 is by 23 greater than P2.

, substitute P1 and P2 with above formulas
, move variables on the left and numbers on the right side
, combine
, divide both sides by -24

Check:
P1 = -15*-2 = 30
P2 = 9*-2 = -18

P1-25 = 30-25 = 5
P2+23 = -18+23 = 5
