You can put this solution on YOUR website!
let n = "a number"
:
Write an equation for exactly what it says:
;
If the product of a number and -15 is decreased by 25, the result is 23 greater than the product of the number and 9.
:
-15n - 25 = 9n + 23
-15n - 9n = 23 + 25
-24n = 48
n = 48%2F%28-24%29
n = -2

You can confirm this answer in the original equation
