You can put this solution on YOUR website!
1) Sum of 3 consecutive odd integers is 165.
\n" ); document.write( ".
\n" ); document.write( "You could use x, y, and z; but then you need 3 equations to solve the 3 unknowns.
\n" ); document.write( "But we are told they a consecutive odd integers, so we can use x, x+2, and x+4.
\n" ); document.write( ".
\n" ); document.write( "x + x+2 + x+4 = 165
\n" ); document.write( "3x + 6 = 165
\n" ); document.write( "3x = 159
\n" ); document.write( "x = 53
\n" ); document.write( "so
\n" ); document.write( "x+2 =55
\n" ); document.write( "x+4 = 57
\n" ); document.write( ".
\n" ); document.write( "Answer: 53, 55, and 57
\n" ); document.write( ".
\n" ); document.write( "2) Sum of consecutive integers is 120
\n" ); document.write( ".
\n" ); document.write( "x + x+1 + x+2 = 120
\n" ); document.write( "3x +3 = 120
\n" ); document.write( "3x = 117
\n" ); document.write( "x = 39
\n" ); document.write( ".
\n" ); document.write( "x+1 = 40
\n" ); document.write( "x+2 = 41
\n" ); document.write( ".
\n" ); document.write( "Answer: 39, 40, and 41
\n" ); document.write( ".
\n" ); document.write( "Done. \n" ); document.write( "

\n" );
