Ok we need to find three consecutive intergers.
\n" ); document.write( "Lets call the smallest interger x
\n" ); document.write( "So if the other two intergers are consecutive then
\n" ); document.write( "the second integer equals x+1
\n" ); document.write( "and the last interger equals x+2
\n" ); document.write( "Given: the sum of three consecutive intergers is -240
\n" ); document.write( "Now write and equation to express this and solve for x:
\n" ); document.write( "(x)+(x+1)+(x+2) = -240
\n" ); document.write( "x+x+1+x+2 = -240
\n" ); document.write( "3x + 3 = -240
\n" ); document.write( "3x = -243
\n" ); document.write( "x = -81\r
\n" ); document.write( "\n" ); document.write( "use this to find the other intergers
\n" ); document.write( "second interger = x+1
\n" ); document.write( "second interger = -81+1
\n" ); document.write( "second interger = -80
\n" ); document.write( "----------------------
\n" ); document.write( "third interger = x+2
\n" ); document.write( "third interger = -81+2
\n" ); document.write( "third interger = -79
\n" ); document.write( "Answer: the intergers are -81, -80, -79
\n" ); document.write( "Check answers:
\n" ); document.write( "The three intergers should add up to -240
\n" ); document.write( "(-81)+(-80)+(-79) = -240
\n" ); document.write( "-240 = -240
\n" ); document.write( " \n" ); document.write( "
\n" );
