Set z equal to the difference between 14w and 7.

Practice makes perfect

It is given that 7 is subtracted from 14w. In other words, the expression is 14w minus 7. 14w- 7 We are also told that the result of this operation is z. Thus, we can set the above expression equal to z. z= 14w- 7 The equation we got is the same as in option D.
