Question

Solve the following system using the substitution method:
6x - 2y = -4
y = 3x + 2

Answer 1

Look here in the attachments: thanks! :)

Answer 2

which one to choose? thanks. :)

Answer 3

Wait, you have two accounts?

Answer 4

Anyway, you have:\[6x - 2y =-4\tag{1}\]Can you solve for \(y\) in \((1)\)?

Answer 5

Yeah two accounts for no reason: sorry about that. :)

Answer 6

OK, do you know how to get the equation \(6x - 2y = -4\) in the form \(y =\cdots\)?

Answer 7

yeah linear right? y = 3 x+2 ?

Answer 8

then what?

Answer 9

Yes!

Answer 10

So you have the SAME EQUATIONS!

Answer 11

That means that \(y\) is dependent on \(x\).

Answer 12

oh thanks! :)
