The sum of three consecutive numbers is 600. What is the least of these three numbers? \r
\n" ); document.write( "\n" ); document.write( "Let x be the first unknown number. The numbers are consecutive, so the other two would be; x+1, x+2\r
\n" ); document.write( "\n" ); document.write( "We now have:\r
\n" ); document.write( "\n" ); document.write( "x+(x+1)+(x+2)=600\r
\n" ); document.write( "\n" ); document.write( "Now we solve the equation for x,\r
\n" ); document.write( "\n" ); document.write( "We can add all the x's together; 3x+3=600\r
\n" ); document.write( "\n" ); document.write( "Now we subtract the 3 from both sides;
\n" ); document.write( " 3x+3-3=600-3
\n" ); document.write( " 3x = 597
\n" ); document.write( "Now we divide the 3 from both sides;
\n" ); document.write( "3x/3 = 597/3\r
\n" ); document.write( "\n" ); document.write( "We are left with x=199
\n" ); document.write( "check:
\n" ); document.write( "now we can add the numbers placing 199 for x;\r
\n" ); document.write( "\n" ); document.write( "199+(199+1)+(199+2)=600\r
\n" ); document.write( "\n" ); document.write( "199+200+201=600\r
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
\n" );
