.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "            It can be solved in much simpler way.\r
\n" ); document.write( "\n" ); document.write( "            You do not need to use the system of two equations.\r
\n" ); document.write( "\n" ); document.write( "            One equation is totally enough.\r
\n" ); document.write( "

\r\n" );
document.write( "Let x be the Shauna's age;\r\n" );
document.write( "\r\n" );
document.write( "then the Jason's age is 3x years.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "In 4 years time, the Shauna's age will be (x+4) years, while the Jason's age will be (3x+4) years.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "The condition says\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "    (x+4) + (3x+4) = 56  years.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "It is your basic equation. Simplify it and solve for x\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "    4x + 8 = 56\r\n" );

document.write( "     x = \"48%2F4\" = 12.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "ANSWER.  Shauna is 12 years old;  Jason is 3*12 = 36 years old.\r\n" );

\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "
\r\n" );
document.write( "In 4 years, the sum of their ages will be 56  ----  hence, the sum of their ages now  is 56-4-4 = 48 years.\r\n" );

document.write( "\r\n" );
document.write( "At the same time, Jason's age is 3 times Shauna's age  --- hence, they are 12 and 36 years,\r\n" );
document.write( "and this simple calculation you can do in your mind (!), obtaining the SAME ANSWER.\r\n" );
