3x-2y=9
\n" ); document.write( "-7x+y=12\r
\n" ); document.write( "\n" ); document.write( "------------------------
\n" ); document.write( "Multiply thru the 2nd equation by 2:
\n" ); document.write( "3x - 2y = 9
\n" ); document.write( "-14x+2y = 24
\n" ); document.write( "------------------
\n" ); document.write( "Add the equations and solve for \"x\":
\n" ); document.write( "-11x = 33
\n" ); document.write( "x = -3
\n" ); document.write( "-------------------
\n" ); document.write( "Substitute into -7x+y = 12 and solve for\"y\":
\n" ); document.write( "-7x + y = 12
\n" ); document.write( "-7(-3) + y = 12
\n" ); document.write( "y = -9
\n" ); document.write( "========================
