\[y=\frac{ 4 }{ 5 }x-\frac{ 3 }{ 5 }\]

How did you get that??
OpenStudy (haleyelizabeth2017):
I thought standard form was Ax+By=c
OpenStudy (anonymous):
Oh so move the x's to one side then the y's then the answer?
OpenStudy (haleyelizabeth2017):
I can walk you through how to get it if you'd like?

yeah, sorry i got it wrong

Please do @haleyelizabeth2017
OpenStudy (haleyelizabeth2017):
Okay, so what we want to do first is distribute the 4 to the parenthesis (x-3). Which gives us...?
OpenStudy (anonymous):
2 + 4*x + 12 + 2 = 4 + 5y ?
OpenStudy (haleyelizabeth2017):
It would actually be -12 :) So
2+4x-12+2=4+5y

Then, we want to combine like terms. So 2+2-12 is what?
OpenStudy (anonymous):
8
OpenStudy (haleyelizabeth2017):
-8 actually
OpenStudy (haleyelizabeth2017):
So...
-8+4x=4+5y, then we add 8 to both sides to get 4x=12+5y
Then we want to subtract 5y from both sides to get it in standard form. This gives us 4x-5y=12 as our final answer :)
