2x/3 + 3y/4 = 11/12
\n" ); document.write( "x/3 + 7y/18 = 1/2
\n" ); document.write( "-------
\n" ); document.write( "Multiply thru 1st equation by 12
\n" ); document.write( "Multiply thru 2nd equation by 18
\n" ); document.write( "----------------------------------------
\n" ); document.write( "8x + 9y = 11
\n" ); document.write( "6x + 7y = 9
\n" ); document.write( "------------------------
\n" ); document.write( "Multiply thru 1st equation by 6
\n" ); document.write( "Multiply thru 2nd equation by 8
\n" ); document.write( "---------------------------------------
\n" ); document.write( "48x + 54y = 66
\n" ); document.write( "48x + 56y = 72
\n" ); document.write( "-----------------------
\n" ); document.write( "Subtract 1st from 2nd1st and solve for \"y\":
\n" ); document.write( "2y = 6
\n" ); document.write( "y = 3
\n" ); document.write( "---------
\n" ); document.write( "Substitute into 6x+7y = 9 to solve for \"x\":
\n" ); document.write( "6x + 7*3 = 9
\n" ); document.write( "6x = -12
\n" ); document.write( "x = -2
\n" ); document.write( "----------------------
