What is the consecutive number of which 4 over 7 of the sum of first and second
\n" ); document.write( " equals the third numbers decrease by 1?
\n" ); document.write( ":
\n" ); document.write( "Three consecutive numbers: x, (x+1), (x+2)
\n" ); document.write( ":
\n" ); document.write( "\"4%2F7\"(x + (x+1)) = (x+2) - 1
\n" ); document.write( "\"4%2F7\"(2x+1) = (x + 1)
\n" ); document.write( "Multiply both sides by 7
\n" ); document.write( "4(2x + 1) = 7(x + 1)
\n" ); document.write( ":
\n" ); document.write( "8x + 4 = 7x + 7
\n" ); document.write( "8x - 7x = 7 - 4
\n" ); document.write( "x = 3
\n" ); document.write( ";
\n" ); document.write( "Numbers are: 3, 4, 5
\n" ); document.write( ";
\n" ); document.write( ":
\n" ); document.write( "See if that works in the statement:
\n" ); document.write( "\"4/7 of the sum of first and second equals the third numbers decrease by 1\"
\n" ); document.write( "\"4%2F7\"(3+4) = (5) - 1
\n" ); document.write( "\"4%2F7\"(7) = 4
\n" ); document.write( "4 = 4 \n" ); document.write( "
\n" );
