You can put this solution on YOUR website!
it helps to label your equations. lets say (3x+y=5 is \"1\" and the other is \"2\"\r
\n" ); document.write( "\n" ); document.write( "solve each equation for y\r
\n" ); document.write( "\n" ); document.write( "\"1\" ----- y=-3x+5
\n" ); document.write( "\"2\" ----- y=2x-10\r
\n" ); document.write( "\n" ); document.write( "since both equations both equal \"y\" you can set them equal to eachother\r
\n" ); document.write( "\n" ); document.write( "-3x+5=2x-10
\n" ); document.write( "solve this equation for \"X\"
\n" ); document.write( "-5x=-15
\n" ); document.write( "x=3\r
\n" ); document.write( "\n" ); document.write( "put the value of \"3\" into the first (or second) equation \r
\n" ); document.write( "\n" ); document.write( "in \"1\" 3(3)+y=5
\n" ); document.write( "9+y=5
\n" ); document.write( "y=-4
\n" ); document.write( "check your answers in the other equation as well
\n" ); document.write( "
