Algebra.Com's Answer #149481 by RAY100(1637) ![]() You can put this solution on YOUR website! Let x = Quotient of above \n" ); document.write( ". \n" ); document.write( "Then 5x+4 = 4n-1,,,,, that is quotient times divisor is 4 less than dividend,,,hence remainder 4 \n" ); document.write( ". \n" ); document.write( " 5x +5 =4n \n" ); document.write( ". \n" ); document.write( "(5x+5) / 4 =n \n" ); document.write( ". \n" ); document.write( "itterate x until n = integer \n" ); document.write( ". \n" ); document.write( "@ x=7,,,n=10 \n" ); document.write( ". \n" ); document.write( "check \n" ); document.write( ". \n" ); document.write( "( 4*10 -1) / 5 = 39/5 = 7 rem4 \n" ); document.write( " |
