Guest (Customer)
[00:00:00] I need help on my multi step equation

Rick R (Tutor)
[00:00:12] Hi there, what seems to be giving you a hard time today?

Guest (Customer)
[00:00:58] im stuck on #4. 9(*
[00:02:14] 9(I+2)= 3(I-2) I=

Rick R (Tutor)
[00:02:36] Ok
[00:03:01] Well the trick here is to get the I all by its self on one side of the equation
[00:03:07] do you know how to go about doing that?

Guest (Customer)
[00:03:18] ya

Rick R (Tutor)
[00:03:33] ok, why dont you show me
[00:06:58] ok hold on a second
[00:07:04] i think this is where youre running into trouble
[00:07:35] the first step in this process would be to distribute the 9 and the 3 or expand the equation. let me show you

Guest (Customer)
[00:07:48] ok
[00:09:39] ok

Rick R (Tutor)
[00:09:48] when you have an expression like I + 2 in parentheses
[00:10:09] and a number right before it
[00:10:24] you will have to expand like i wrote down
[00:10:27] does that make sense?

Guest (Customer)
[00:10:38] yes

Rick R (Tutor)
[00:10:57] do you know how to solve for I from this point?

Guest (Customer)
[00:11:28] yes

Rick R (Tutor)
[00:11:38] ok
[00:11:43] why dont you walk me through it

Guest (Customer)
[00:11:49] ok
[00:13:03] because in school the equal sign is minus

Rick R (Tutor)
[00:13:34] what do you mean

Guest (Customer)
[00:14:46] my teacher says the equal sign is making the three positive

Rick R (Tutor)
[00:15:26] yes the 3 is a positive number
[00:15:41] but if you were to multiply it by -2
[00:15:44] then it becomes -6
[00:16:00] would you like me to show you the rest of the steps?

Guest (Customer)
[00:16:11] yes

Rick R (Tutor)
[00:16:15] ok
[00:18:13] does that make sense?

Guest (Customer)
[00:18:11] ok
[00:18:18] yes

Rick R (Tutor)
[00:18:46] Do you have any other questions about anything we went over today?
