Question 215608
When  we  do  a  word  problem,,we  are  looking  for  two  things
.
(1)  the  operations  required(add,  subtract,  multiply,,divide,etc...)
.
(2)  the  number  to  use,,,,(often  we  use  simpler  numbers  to  define  the  operation,then  substitute  the  "real" numbers.
.
.
Key  words  in  this  problem  include,,,"is  the  same  as"  or  equals (=)
.
"difference" or  subtraction(-)
.
" less  than" or  also  subtraction(-)
.
Let  x = number
.
Now  just  write  the  sentence
.
x-9 = 35 -x,,,,,,,add  x,,, add  9,,,to  both  sides
.
2x = 44,,,,,,divide  by  2
.
x=22
.
.
check,,22-9 =35-22 = 13,,,,ok
.
