Question

The quotient of 2 times a number and 19

Answer 1

This one is worded oddly, but I think it's going to be:
(2x)/19

Answer 2

Answer: The equation is: (2*N)/19 for a number N

Explanation:

Here we have the sentence "the quotient of 2 times a number and 19"

this means the quotient (a division) between:

2 times a number.

This is, for a given number N, equal to 2*N

and the number 19.

So the sentence "the quotient of 2 times a number and 19"

is equivalent to "2*N divided by 19" or (2*N)/19
