Question

What is the value of w?

5(9 − 3) = w • 9 – 5 • 3

Answer 1

45 and 2

Answer 2

2 is wrong...
5 x -3 remember we are multiplying not adding

Answer 3

ok

Answer 4

So what is 5 x -3?

Answer 5

srry afk -15

Answer 6

Good so we have
\[\huge~\rm~ 45-15=w • 9 – 5 • 3 \]
Now we need to multiply the other side
\[\huge~\rm~9(w)-5(3)\]
What do you get when you multiply those?

Answer 7

9w - 15

Answer 8

Well done :)
now we have
\[\huge~\rm~45−15=9w-15\]
Any ideas on what the next step may be?

Answer 9

subtract 15 on both sides?

Answer 10

No we do the opposite of subtraction....remember we are trying to cancel them out

Answer 11

30 - 15 = 9w

Answer 12

oh ok

Answer 13

\[\huge~\rm~45−15+15=9w−15+15\]

Answer 14

45 - 30 = 9w - 30

Answer 15

-15+15=?
it is not -30

Answer 16

oh ok 15 then

Answer 17

oh i didnt say - 30 i just meant 30

Answer 18

Try again.
if you have -15 and add 15 what do you get?

Answer 19

yes sorry its 0

Answer 20

Yes so \[\huge~\rm~45=9w\]
Well now that those cancel out what is the next step?

Answer 21

its ok i learned it in 4th grade im just a little off track

Answer 22

add 45 on both sides

Answer 23

Now we are trying to isolate the w right? So we need to divide both sides by 9w

Answer 24

ok

Answer 25

Let me know what you get as an answer

Answer 26

-36 = w

Answer 27

The w part is correct but what is 45/9 ?
