the sum of three numbers is 6. The third number is the sum of the first and second number. The first number is one more than the third number. Find the numbers.
\n" ); document.write( "-----
\n" ); document.write( "Equations:
\n" ); document.write( "x + y + z = 6
\n" ); document.write( "z = x+y
\n" ); document.write( "x = z+1
\n" ); document.write( "------
\n" ); document.write( "Substitute for x to get:
\n" ); document.write( "z = z+1+y
\n" ); document.write( "Therefore y = -1
\n" ); document.write( "----------------------
\n" ); document.write( "Substitute for \"x\" and for \"y\":
\n" ); document.write( "z+1 + (-1) + z = 6
\n" ); document.write( "2z = 6
\n" ); document.write( "z = 3
\n" ); document.write( "--------------
\n" ); document.write( "Since x = z+1, x = 4
\n" ); document.write( "-----
\n" ); document.write( "Solution:
\n" ); document.write( "x = 4
\n" ); document.write( "y = -1
\n" ); document.write( "z = 3
