Which equation does the graph of the systems of equations solve? https://lss.brainhoney.com/Resource/22181743,AD2,0,C,3,0/Assets/72257_53b5b170/0608_g6_q3.jpg

OpenStudy (vera_ewing):

@UnkleRhaukus (1/3)x + 3 = x-1 is this the answer?

OpenStudy (unklerhaukus):

what is the x component of the intersection? what is the solution to that equation?

OpenStudy (vera_ewing):

What do you mean?

OpenStudy (unklerhaukus):

|dw:1428857598523:dw|

OpenStudy (vera_ewing):

(3, -2)

OpenStudy (unklerhaukus):

so the x coordinate is 3

OpenStudy (vera_ewing):

Ohh ok now I get it. So I was right! thank you :)

OpenStudy (unklerhaukus):

now solve (1/3)x + 3 = x-1 take away three from both sides; and take away (1/3)x from both sides

OpenStudy (vera_ewing):

(1/3)x + 3 = x-1 right?

OpenStudy (unklerhaukus):

(1/3)x + 3 = x-1 taking away three from both sides (1/3)x + 3 -3 = x - 1 -3 (simplify this)

OpenStudy (vera_ewing):

(1/3)x=x-4

OpenStudy (unklerhaukus):

good now: take away (1/3)x from both sides

OpenStudy (vera_ewing):

x=x-4-(1/3)

OpenStudy (unklerhaukus):

(1/3)x - (1/3)x = x - 4 - (1/3)x 0 = (2/3)x - 4

OpenStudy (vera_ewing):

ok so what would the answer be?

OpenStudy (unklerhaukus):

0 = (2/3)x - 4 now add 4 to both sides, then times both sides by three finally divide both sides by 2

OpenStudy (vera_ewing):

what did you say? it's not showing up /:

OpenStudy (unklerhaukus):

0 = (2/3)x - 4 now add 4 to both sides, [ ??? ] then times both sides by three [ ??? ] finally divide both sides by 2 x =
