\" 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( "Follow these steps, write an equation for what it says (the word \"is\" usually means \"=\":
\n" ); document.write( "Let x = the 10's digit, Let y = the units digit
\n" ); document.write( "The number will = (10x + y)
\n" ); document.write( ":
\n" ); document.write( "\" The tens digit is four times the units digit\"
\n" ); document.write( " x = 4y
\n" ); document.write( ":
\n" ); document.write( "\" the number is 10 more than nine times the tens digit Find the number.\"
\n" ); document.write( " (10x + y) = 9x + 10
\n" ); document.write( "Do the algebra, subtract 9x and y from both sides:
\n" ); document.write( "10x - 9x = 10 - y
\n" ); document.write( "x = 10 - y
\n" ); document.write( ":
\n" ); document.write( "Remember x = 4y, substitute that for x in the above equation:
\n" ); document.write( "4y = 10 - y
\n" ); document.write( "4y + y = 10; added y to both sides
\n" ); document.write( "5y = 10
\n" ); document.write( " y = 10/5
\n" ); document.write( " y = 2 is the units digit
\n" ); document.write( ":
\n" ); document.write( "10s digit: x = 4y
\n" ); document.write( "x = 4(2)
\n" ); document.write( "x = 8 is the tens digit
\n" ); document.write( ":
\n" ); document.write( "That makes the number 82
\n" ); document.write( ":
\n" ); document.write( "Check solution by seeing if it satisfies the statement:
\n" ); document.write( "\"the number is 10 more than nine times the tens digit\"
\n" ); document.write( " 82 = 9(8) + 10 \n" ); document.write( "
\n" );
