Let the first integer =X
\n" ); document.write( "Therefor the second integer =X+1
\n" ); document.write( "and the third integer = X+2
\n" ); document.write( "The resulting equation is: 4(X+(X+1))=7(X+2)-1\r
\n" ); document.write( "\n" ); document.write( "4(2X+1)=7X+14-1
\n" ); document.write( "8X+4=7X+13
\n" ); document.write( "8X-7X=13-4
\n" ); document.write( "X=9
\n" ); document.write( "The first integer is X=9
\n" ); document.write( "The second integer is X+1=10
\n" ); document.write( "The third integer is X+2=11
\n" ); document.write( "
\n" );
