Six less than seven times a number is the same as nine times the number.  Find the number.
x = the number 

7x - 6 = 9x   {six less than seven times x is equal to nine times x}
-6 = 2x   {subtracted 7x from each side}
x = -3   {divided each side by 2} 

the number is -3

phew.....we found the number!
