x = one number
\n" ); document.write( "y = another number
\n" ); document.write( ".
\n" ); document.write( "3x + 7y = 62
\n" ); document.write( ".
\n" ); document.write( "the difference between x & y = 4
\n" ); document.write( "x - y = 4
\n" ); document.write( "x = y +4
\n" ); document.write( ".
\n" ); document.write( "substitute for x
\n" ); document.write( ".
\n" ); document.write( "3(y+4) +7y = 62
\n" ); document.write( ".
\n" ); document.write( "3y +12 +7y = 62
\n" ); document.write( "10y = 50
\n" ); document.write( "y = 5
\n" ); document.write( ".
\n" ); document.write( "substitute y = 5 to find x
\n" ); document.write( ".
\n" ); document.write( "x = y+4
\n" ); document.write( "x = 5+4
\n" ); document.write( "x = 9
\n" ); document.write( ".
\n" ); document.write( "Always check your answer.
\n" ); document.write( ".
\n" ); document.write( "3(9) + 7(5) = ?
\n" ); document.write( "27 + 35 = 62
\n" ); document.write( "Correct.
\n" ); document.write( ".
\n" ); document.write( "Answer: The two numbers are 5 and 9.
\n" ); document.write( ".
