The tens digit is four times the units digit and the number is 10 more than nine times the tens digit. Find the number.\" \n" ); document.write( "--------------- \n" ); document.write( "Comment: Any two digit number can be written as 10t+u where t is the 10's \n" ); document.write( "digit and u is the units digit. \n" ); document.write( "-------------------------- \n" ); document.write( "Your Problem: \n" ); document.write( "Let your number be 10t+u \n" ); document.write( "EQUATIONS: \n" ); document.write( "t = 4u \n" ); document.write( "10t+u = 9t+10 \n" ); document.write( "-------- \n" ); document.write( "Substitute to get: \n" ); document.write( "10(4u)+u = 9(4u)+10 \n" ); document.write( "40u+u = 36u+10 \n" ); document.write( "5u = 10 \n" ); document.write( "u=2 \n" ); document.write( "------ \n" ); document.write( "Substitute into t=4u to solve for t: \n" ); document.write( "t=4*2=8 \n" ); document.write( "-------- \n" ); document.write( "The number is 82 \n" ); document.write( "================= \n" ); document.write( "Cheers, \n" ); document.write( "Stan H.\r \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
