Question

The product of 9 and a number is 12 less than three times that number.
What is the number?

Answer 1

Lets make this into an equation, have any ideas?

Answer 2

Ok, so we have the product of 9 and a number, 9x. Then, is 12 less, -12. Than three times that number, = 3x. So overall we get 9x-12=3x. Does that make sense?

Answer 3

Did that make sense, it is ok if no.

Answer 4

i didn't understand that sorry

Answer 5

Answer 6

The product of 9 and a number.

That's multiplying 9 with an known number, which we can call 'x'.

So we can write that as '9x'.

The 'is' separates the two halves of the question with an equal sign(=).

So far we have 9x =

'12 less than three times that number'

12 less than means that we will subtract 12 from whatever comes next.

three times that number, which is the same thing as 3x, so we subtract 12 from '3x', giving us 3x - 12.

So our full equation is:

9x = 3x - 12

Can you solve that for 'x'?

Answer 7

Actually I think I did something wrong..lol

Answer 8

Yeah..I think what you did was correct @sleepyjess

Answer 9

Originally I thought the same thing @iGreen

Answer 10

-3

Answer 11

@sleepyjess @iGreen

Answer 12

is this the correct answer @iGreen or @sleepyjess ?

Answer 13

What did you do to get -3?

Answer 14

sleepyjess please answer i need to know if i am correct

Answer 15

i did 9x-12=-3x

Answer 16

Why -3x?

Answer 17

I gave you the equation, 9x-12=3x

Answer 18

You have to solve for x

Answer 19

I GOT IT x=2

Answer 20

@sleepyjess

Answer 21

Yep!

Answer 22

Yep, you got it.. x = 2.

Answer 23

9x - 12 = 3x

Add 12 to both sides:

9x = 3x + 12

Subtract 3x to both sides:

6x = 12

Divide 6 to both sides:

x = 2

Answer 24

Great work. @sleepyjess
