If the second digit of a 2 digit no 3 times of first digit and there position is changed and added to original no the answer is 88 what are digits?
\n" ); document.write( ":
\n" ); document.write( "Let x = the 1st digit
\n" ); document.write( "Let y = the 2nd digit
\n" ); document.write( "Then
\n" ); document.write( "10x + y = \"the number\"
\n" ); document.write( ":
\n" ); document.write( "Write an equation for each statement:
\n" ); document.write( ":
\n" ); document.write( "\"if the second digit of a 2 digit no 3 times of first digit\"
\n" ); document.write( "y = 3x
\n" ); document.write( ":
\n" ); document.write( "\"their position is changed and added to original no the answer is 88\"
\n" ); document.write( "10y+x + 10x+y = 88
\n" ); document.write( "11x + 11y = 88
\n" ); document.write( ":
\n" ); document.write( "Simplify divide by 8, results:
\n" ); document.write( "x + y = 8
\n" ); document.write( ":
\n" ); document.write( "what are digits?
\n" ); document.write( ":
\n" ); document.write( "Substitute 3x for y in the above equation
\n" ); document.write( "x + 3x = 8
\n" ); document.write( "4x = 8
\n" ); document.write( "x = 2 is the 1st digit
\n" ); document.write( "then
\n" ); document.write( "3(2) = 6 is the 2nd digit
\n" ); document.write( ":
\n" ); document.write( "26 is the number
\n" ); document.write( ";
\n" ); document.write( ";
\n" ); document.write( "Check solution 62 + 26 = 88
\n" ); document.write( " \n" ); document.write( "
\n" );
