Answer: The equation is given by: 9- 1/3x = 7 Step-by-step explanation: Let the number be denoted by x. Now, we are given a word phrase as follows one-third of a number less than nine is equal to seven. Now this word phrase could be mathematically expressed as a equation by: one third of x is 1/3 x And this number less than 9 is given by :
9- 1/3x
Now, this number is equal to 7. I.e. we finally have: 9- 1/3x = 7
