Question

2x -3 (4x -2) = 5 (x-1) +8
-> 2x - 12x + 6 = 5x - 5 +8 not sure if I should work with -5 +8 and then bring the 6 over or not help please

Answer 1

A good tip is usually to move the x's on one side and then the regular numbers on the other.

Answer 2

yes that what I was trying to do

Answer 3

Ok, try and then I can correct you if I see something wrong, because what your thinking is correct.

Answer 4

Answer 5

Yes

Answer 6

Answer 7

-15 = -3?

Answer 8

Where is the x?

Answer 9

-15x!! soory

Answer 10

I think I may be wrong.

Answer 11

I think you may be right :) Now what is \[-15x = -3\]

Answer 12

:O oh gosh! okay :) x=0.2

Answer 13

I think your right. Let me just do the calculation on my own.

Answer 14

okay

Answer 15

I get the same answer. Lets hope we both are correct :)

Answer 16

On the original paper when I got this problem wrong, my teacher wrote corrections and once It was at the point of dividing -15 into -3, she simplified it as a fraction. and resulted in 1/5

Answer 17

I would also have simplified it as a fraction :) but they are basically the same :)

Answer 18

alrighty :)

Answer 19

You are an excellent teacher

Answer 20

Since I don't actually have to do anything I would say that your much better at what your doing than what you think.

Answer 21

But you tell me if I'm doing something right or wrong and you remind me to combined terms and such :)

Answer 22

Yeah, but you already know how to do that :)

Answer 23

noo because I second guess and I become unsure! haha

Answer 24

See, you already know that not knowing isn't your problem :) Your problem is that you don't trust yourself. It will go away after you've practiced. Life advice from grumpy old! Good luck onwards :)

Answer 25

xD Thank you!!!
