You can put this solution on YOUR website!
-6x = y
\n" ); document.write( "2x + y = -2\r
\n" ); document.write( "\n" ); document.write( "-6x - y = 0
\n" ); document.write( " 2x + y = -2
\n" ); document.write( "Add together
\n" ); document.write( " -4x = -2
\n" ); document.write( " x = -2/-4
\n" ); document.write( " x = 1/2
\n" ); document.write( "Substitute x = 1/2 in
\n" ); document.write( "2x + y = -2
\n" ); document.write( "2(1/2) + y = -2
\n" ); document.write( " 1 + y = -2
\n" ); document.write( " y = -2 -1
\n" ); document.write( " y = -3
\n" ); document.write( " x= 1/2 y = -3\r
\n" ); document.write( "\n" ); document.write( "x - y = 1
\n" ); document.write( "y = 3x + 3\r
\n" ); document.write( "\n" ); document.write( " x - y = 1
\n" ); document.write( "-3x + y = 3
\n" ); document.write( "Add
\n" ); document.write( " -2x = 4
\n" ); document.write( " x = 4/-2
\n" ); document.write( " x = -2
\n" ); document.write( "Substitute x = -2 in
\n" ); document.write( "x - y = 1
\n" ); document.write( "-2 - y = 1
\n" ); document.write( " -y = 1 + 2
\n" ); document.write( " -y = 3
\n" ); document.write( " y = -3
\n" ); document.write( "x = -2 y = -3
\n" ); document.write( "Hope this helps.
