The product of 9 and a number is 12 less than three times that number. What is the number?
NEED HELP PRONTO!
First, choose a variable to represent the number. Let's use x for the number.
If the number is x, then what is "the product of 9 and the number"?
9 x n = 3 x n - 12. I can make the equation, but I am having trouble solving it.
Ok. Your equation is good. You used n for the variable.
Ok, now let's solve it together.
9n = 3n - 12 We want all n's on the left side, so we subtract 3n from both sides.
9n - 3n = 3n - 3n - 12 That eliminates the 3n from the right side giving us: 6n = -12 Ok so far?
so you subtract 3n from 9n right?
sorry, internet crshed.
I just really need the answer so my dad will stop bugging me.
Yes.
Now that you have 6n = -12 you want n alone. n is being multiplied by 6, so divide both sides by 6 6n/6 = -12/6 n = -2
omg thank you.
You don't know how much you've made my day.
