[00:00:00] using the method of addition 2x+5y=3 -x+3y=-7

[00:00:10] Welcome to Tutor.com ! Let's get started.

angela (Customer)
[00:00:15] hi

Gretchen C (Tutor)
[00:00:23]
[00:00:33] ever done a problem like this before?

angela (Customer)
[00:00:42] yeah

Gretchen C (Tutor)
[00:00:55] will you use substitution or elemination?
[00:01:04] elimination

angela (Customer)

Gretchen C (Tutor)
[00:02:08] that method I am not familiar with for solving simultaneous equations
[00:02:27] I think it is the same as elimination though

angela (Customer)
[00:02:30] yeah it is

Gretchen C (Tutor)
[00:02:41] OK

angela (Customer)
[00:02:53] i dont know which on to elimiate though

Gretchen C (Tutor)
[00:03:13] any one is fine, but I usually use the one
[00:03:26] that requires the least multiplication
[00:03:37] like -x times 2 to get -2x
[00:04:12] looks good so far
[00:05:28] You got it!

angela (Customer)
[00:05:35] right

Gretchen C (Tutor)
[00:05:47] now for the x...
