Hi,
I am trying to solve the following problem for algebra by eliminiation. Unfortuantely it comes out so that I do not understand it. The question is :
-6y+2x=8
3y-x=9
I multiply the bottom one by 2.....
-6y+2x=8
6y-2x=18
the add the 2 equations together...
0-0=26
which I don't understand?
Thanks for any help,
Nate

Thanks to all for the quick replies. They were very helpful.

This means those two equations have no intersection(no place on the line where their x,y values are the same). This makes the system you listed a inconsistent system with no solution.

The people above me are correct. There is no solution. If you solve each equation individually for y, you will see that their graphs are parallel.

these equations has no solution
Not all linear equations have solutions
If you plot this 2 equations, there will be 2 lines
these 2 lines have no common point
i.e they do not intersect, they are parralel, no intersection point

there wont be any x intercepts because its zero but there will be a y intercept because x=0 so you need to subsitute x in one of the equations

Hello
This means rhat the system has no dolution
When a system elim. two variables as this one did it mean that the system has no solution

That shows that you have an inconsistent system.
There is no solution to the original system.

Your answer means there is no x and y value that will satisfy both equations.

This has no answer - are you sure you read it right, or could it be a trick question?

The x and y coeficients and variables cancell.
There is no solution.
