You can put this solution on YOUR website!
The first is 2y=x-4 so y=(1/2)x-2
\n" ); document.write( "the second is 8y=4x-10, so y= (1/2)x-5
\n" ); document.write( "\"graph%28300%2C300%2C-10%2C10%2C-10%2C10%2C%281%2F2%29x-2%2C%281%2F2%29x-5%29\"\r

\n" ); document.write( "\n" ); document.write( "Can solve by letting x=2y+4 in the first and substitute in the second
