Algebra.Com's Answer #233152 by mananth(16946)![]() ![]() You can put this solution on YOUR website! The sum of the digits of the two-digit number is 8. The number with the digits interchanged is 14 more than 8 times the units digit of the original number. Find the original number.\r \n" ); document.write( "\n" ); document.write( ".. \n" ); document.write( "let ten's digit be x \n" ); document.write( "and units digit be y \n" ); document.write( "x+y=8..................1 \n" ); document.write( "the number = 10x+y \n" ); document.write( ".. \n" ); document.write( "10y+x = 14+8y \n" ); document.write( "10y-8y+x=14 \n" ); document.write( "2y+x=14................2 \n" ); document.write( ".. \n" ); document.write( "subtract equation 2 from equation1 \n" ); document.write( "(x+y)-(2y+x)=8-14 \n" ); document.write( "x+y-2y-x=-6 \n" ); document.write( "-y=-6 \n" ); document.write( "y=6 \n" ); document.write( ".. \n" ); document.write( "Plug the value of y in equation 1 \n" ); document.write( "x+6=8 \n" ); document.write( "x=2 \n" ); document.write( "The number = 26 \n" ); document.write( " |
