Question 263407: Solve the following system of linear equations. If possible, express your answer as an ordered pair (x,y). Also, tell whether the system of equations is “independent”, “inconsistent”, or “dependent”.
2x-4y=8
x-2y=4

You can put this solution on YOUR website!
Here is our original system
(i) 2x-4y=8
(ii) 1x-2y=4
step 1 - multiply (ii) by -2 to get
(iii) -2x+%2B+4y+=+-8
add (ii) and (iii) to get
(iv) 0+%2B+0+=+0
this mans that we have the same equations but in disguise.
These equations are "dependent"
