Let the number = X
Then to get four less you need to subtract 4 from x so you have X-4.
Then that equals 17, so the equation would be:
x - 4 = 17
The equation of the sentence 'four less than a number is 17' is x – 4 = 17
Let the number be x
Four less than the number means x - 4
Therefore,
Four less than a number is 17 means x – 4 = 17
Therefore, option x – 4 = 17 is the correct answer
