You can put this solution on YOUR website!
There is no solution, they don't intersect! There are many ways to show this is true. One is you can change them both to the form y=mx+b. Then you will see m=2 for both, so they are parallel lines. Parallel lines never intersect. Another way to show there is no solution is with substitution. The first equation says 2x-y=4. That means whenever you see 2x-y, you can substitute in 4. So, the second equation, 2x-y=6 becomes 4=6. This cannot be true, so there is no solution. \n" ); document.write( "
