let t = the ten's digit
\n" ); document.write( "let u = the units
\n" ); document.write( "then
\n" ); document.write( "10t + u = \"the number\"
\n" ); document.write( ":
\n" ); document.write( "Write an equation for each statement:
\n" ); document.write( ":
\n" ); document.write( "\"The sums of the digits of a two digit number is 14.\"
\n" ); document.write( "t + u = 14
\n" ); document.write( "u = (14-t); we can use this form for substitution
\n" ); document.write( ":
\n" ); document.write( "\"If 4 is added to the number, the result is seven times the units digit.\"
\n" ); document.write( "(10t+u) + 4 = 7u
\n" ); document.write( "10t + 4 = 7u - u
\n" ); document.write( "10t + 4 = 6u
\n" ); document.write( "replace u with (14-u) from the 1st statement equation
\n" ); document.write( "10t + 4 = 6(14-t)
\n" ); document.write( "10t + 4 = 84 - 6t
\n" ); document.write( "10t + 6t = 84 - 4
\n" ); document.write( "16t = 80
\n" ); document.write( "t = 80/16
\n" ); document.write( "t = 5 is the 10's digit
\n" ); document.write( "then
\n" ); document.write( "14 - 5 = 9 is the units
\n" ); document.write( ":
\n" ); document.write( "59 is the number
\n" ); document.write( ":
\n" ); document.write( ":
\n" ); document.write( "Confirm this in the 2nd statement;
\n" ); document.write( "\"If 4 is added to the number, the result is seven times the units digit.\"
\n" ); document.write( "4 + 59 = 7(9)
\n" ); document.write( ":
