19≤13–d what is the anwser and how would you solve it ?

the answer is ≤-6 because in order for the number 13 to be higher than the number 19 we need to subtract a negitive number. This is because when subtracting a positive number the number goes down but you cant subtract what isnt there. subtracting a negitive from a positive makes the number go up. so if 19≤13 that means less than or equal to. so 13 is transformed from 13 to 19 or higher. 19 is 6 higher than 13 so it can be equal or lower
