y= x + 12
\n" ); document.write( "8x + 14y = 144
\n" ); document.write( "--------
\n" ); document.write( "Sub for y into the 2nd eqn
\n" ); document.write( "8x + 14(x+12) = 144
\n" ); document.write( "8x + 14x + 168 = 144
\n" ); document.write( "22x = -24
\n" ); document.write( "x = -12/11
\n" ); document.write( "-----------
\n" ); document.write( "y = -12/11 + 12
\n" ); document.write( "y = 120/11
