John's age now = x + 6\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Jill's age now = x\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "John's age 5 years ago = (x + 6) - 5\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Jill's age 5 years ago = x - 5\r
\n" ); document.write( "\n" ); document.write( "====================================\r
\n" ); document.write( "\n" ); document.write( "(x + 6) - 5 = 3(x - 5)\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "x - 1 = 3x - 15\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "x - 3x = -15 + 1\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "-2x = -14\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "x = -14/-2\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "x = 7\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Jill is 7 year old.\r
