The sum of two positive integers is 108. One integer is three times as great as the other. Find the integers
\n" ); document.write( ".
\n" ); document.write( "Let x = smaller integer
\n" ); document.write( "and y = larger integer
\n" ); document.write( ".
\n" ); document.write( "x+y = 108 (equation 1)
\n" ); document.write( "y = 3x (equation 2)
\n" ); document.write( ".
\n" ); document.write( "substitute the value of y from equation 2 into equation 1 and solve for x:
\n" ); document.write( "x+y = 108
\n" ); document.write( "x+3x = 108
\n" ); document.write( "4x = 108
\n" ); document.write( "x = 27
\n" ); document.write( ".
\n" ); document.write( "substitute the above into equation 2 and solve for y:
\n" ); document.write( "y = 3x
\n" ); document.write( "y = 3(27)
\n" ); document.write( "y = 81
\n" ); document.write( ".
\n" ); document.write( "The two integers are 27 and 81 \n" ); document.write( "
\n" );
