Aneta A (Tutor)
[00:00:05] Welcome to tutor.com
[00:00:16] Let me copy your question on the board
[00:00:42] do you see it on the board?

Janeysi (Customer)
[00:01:47] yes

Aneta A (Tutor)
[00:00:59] ok
[00:01:04] what is the instruction with this problem?
[00:01:40] what does the problem ask us to do?

Janeysi (Customer)
[00:02:31] just to solve it

Aneta A (Tutor)
[00:01:45] ok
[00:01:54] do you know how to start with this problem?

Janeysi (Customer)
[00:03:19] ummm no that is were i am completely stuck

Aneta A (Tutor)
[00:02:46] first we need to simplify the left side
[00:03:01] we need to remove that parenthesis around 2t-1
[00:03:13] to do that, we need to distribute -3 into 2t-1
[00:03:19] do you know how to do that?

Janeysi (Customer)
[00:04:59] okay so would it be 6t+3

Aneta A (Tutor)
[00:04:25] -6t or +6t?

Janeysi (Customer)
[00:05:31] -6t

Aneta A (Tutor)
[00:04:46] very good
[00:04:49] let me copy that
[00:05:17] do you know what the next step might be?

Janeysi (Customer)
[00:06:53] add 3 to 19

Aneta A (Tutor)
[00:06:11] you are right
[00:06:22] so what do we get on the left side of the equal sign?

Janeysi (Customer)
[00:07:47] 22-6t

Aneta A (Tutor)
[00:07:07] great
[00:07:11] let me copy that on the board
[00:07:30] do you know what to do next?

Janeysi (Customer)
[00:08:42] subtract 22 from 10

Aneta A (Tutor)
[00:08:01] you are right
[00:08:05] what do we get when we do that?

Janeysi (Customer)
[00:09:42] -6t= -12 which then t=2

Aneta A (Tutor)
[00:09:01] you are right, good job!
[00:09:12] do you have any questions about this problem?

Janeysi (Customer)
[00:10:44] nope. thank you for the help! 😊

Aneta A (Tutor)
[00:10:01] you are welcome
[00:10:08] May I help you with any more questions?

Janeysi (Customer)
[00:12:09] okay so what if its a problem like this: 7x-2(3x+4)=15

Aneta A (Tutor)
[00:11:28] let me open a new board
[00:11:57] we pretty much follow the same steps
[00:12:07] first we need to remove the parenthesis around 3x+4
[00:12:10] can you give it a try?

Janeysi (Customer)
[00:13:35] okay so would you multiply by -2

Aneta A (Tutor)
[00:12:49] right
[00:12:53] what do we get when we do that?

Janeysi (Customer)
[00:14:31] 7x-6x-8=15

Aneta A (Tutor)
[00:13:51] right
[00:14:06] what do we do next?

Janeysi (Customer)
[00:15:27] add 8 to both sides

Aneta A (Tutor)
[00:14:40] right

Janeysi (Customer)
[00:15:49] x=23

Aneta A (Tutor)
[00:15:12] good job!
