You can put this solution on YOUR website!
X-4Y=4\r
\n" ); document.write( "\n" ); document.write( "x + 4y= -4
\n" ); document.write( "-x -x\r
\n" ); document.write( "\n" ); document.write( "4y=-4-x
\n" ); document.write( "divide both sides by 4
\n" ); document.write( "y=-x\r
\n" ); document.write( "\n" ); document.write( "then you replace y by -1 (because -x is -1) so
\n" ); document.write( "x+4(-1)=-4
\n" ); document.write( "x+-4=-4
\n" ); document.write( "add 4 to both sides
\n" ); document.write( "x=0 so
\n" ); document.write( "(-1,0)\r
\n" ); document.write( "
