Question 213820: Hello again im having trouble with this one too. help please.

You can put this solution on YOUR website! (1/2)x - (1/8)y = -(1/4),,,,,mult by 8
.
4x -y=-2,,,,,,,,mult by -1
.
-4x +y = 2
.
But this matches the second equation, therefore the equations are coincident(lay of top of each other).
.
Therefore there are infinitely many solutions
.
Answer by stanbon(75887) (Show Source):
You can put this solution on YOUR website! Get rid of the fractions:
-------------------
(1/2)x-(1/8)y=-1/4
-4x+y=2
---------------------------
4x - y = -2
-4x+ y = 2
----------------
Add those and you will get:
0 = 0
===================================
That means the two equations are really one.
The solution is any point that fits
into (x, 4x+2), for any value of x.
============================================
