You can put this solution on YOUR website!
1) let x be my age, y is my sister's age, z is my brother's age
\n" ); document.write( ":
\n" ); document.write( "x + y + z = 32
\n" ); document.write( ":
\n" ); document.write( "x = 2y and z = x + 2
\n" ); document.write( ":
\n" ); document.write( "also z = 2y + 2 (substitute for x)
\n" ); document.write( ":
\n" ); document.write( "therefore we have
\n" ); document.write( ":
\n" ); document.write( "2y + y + (2y + 2) = 32
\n" ); document.write( ":
\n" ); document.write( "5y + 2 = 32
\n" ); document.write( ":
\n" ); document.write( "5y = 30
\n" ); document.write( ":
\n" ); document.write( "y = 6
\n" ); document.write( ":
\n" ); document.write( "*************************
\n" ); document.write( "I am 6 * 2 = 12 years old
\n" ); document.write( "*************************
\n" ); document.write( ":
\n" ); document.write( "2.1) variable is y
\n" ); document.write( ":
\n" ); document.write( "2.3) constant term is -6
\n" ); document.write( ": \n" ); document.write( "
\n" );
