You can put this solution on YOUR website!
-x + 2y = 11.....1
\n" ); document.write( "3x - 2y = -13....2
\n" ); document.write( "Multiply (1) by 3
\n" ); document.write( "-3x + 6y = 33....3
\n" ); document.write( "3x - 2y = -13....2
\n" ); document.write( "Add (3) + (2)
\n" ); document.write( "4y = 20
\n" ); document.write( "y = 5
\n" ); document.write( "Substitute y = 5
\n" ); document.write( "into (2)
\n" ); document.write( "3x - 2y = -13...2
\n" ); document.write( "3x -2(5) = -13
\n" ); document.write( "3x - 10 = -13
\n" ); document.write( "3x = -13 + 10
\n" ); document.write( "3x = -3
\n" ); document.write( "x = -1
\n" ); document.write( "x = -1, y = 5.
