Question

How would you solve a problem like -6w < 84 Please help! :)

Answer 1

Multiply both sides by -1. Can you do that for me?

Answer 2

So I multiply -6 and 84 by -1 right?

Answer 3

No

Answer 4

You have to multiply -1 to both sides which means you can only multiply it to the right side of the problem.

Answer 5

So only 84?

Answer 6

Yes

Answer 7

Ok and then once I do that I will get my answer right?

Answer 8

No

Answer 9

Tell me what you got after you multiplied -1 to both sides.

Answer 10

Ok

Answer 11

-84

Answer 12

Correct.

And multiply by a -1 number you have to do what to the inequality symbol?

Answer 13

Sorry, I mean negative number (not -1 number)

Answer 14

Change it?

Answer 15

Correct, you reverse it.

So what would the problem look like right now after you multiplied -1 to both sides and reversed the symbol?

Answer 16

w > -14 or positive 14

Answer 17

What?? how did you get that...?

Answer 18

After you did that your problem should look like this: 6w > -84

Answer 19

Well, it's a multiple choice problem so I taught that that would be your final answer

Answer 20

Do you know the next step of 6w > -84 ?

Answer 21

No

Answer 22

Divide both sides by 6.

Answer 23

Answer 24

Left side cancels out, and what's -84 divided by 6?
