You can put this solution on YOUR website!
-2x-5y= 9
\n" ); document.write( "3x+11y= 4
\n" ); document.write( "-----------
\n" ); document.write( "Multiply thru top equation by 3
\n" ); document.write( "Multiply thru bottom equation by -2
\n" ); document.write( "------------------------------
\n" ); document.write( "-6x - 15y = 27
\n" ); document.write( "-6x - 22y = -8
\n" ); document.write( "----------------------
\n" ); document.write( "Subtract to solve for \"y\":
\n" ); document.write( "7y = 35
\n" ); document.write( "----
\n" ); document.write( "y = 5
\n" ); document.write( "---------
\n" ); document.write( "Solve for \"x\" using -2x - 5y = 9
\n" ); document.write( "-2x -25 = 9
\n" ); document.write( "-2x = 34
\n" ); document.write( "x = -17
