Step-by-step explanation:
Every point on the line 3/7x -1 is a solution
Unless there is another line provided...
This is an example of the commutative property of multiplication.
That property states:

So using that property, we can figure out that
3 should be in the blank.

Answer: J=12
Explanation: To make this equation easier to solve, you can make everything a whole number (a.k.a. Remove the fractions). To do so, you can multiply everything in this equation by the Least Common Multiple (LCM) of all the denominators, which is 12. The equation now becomes:
-4=3J-40
Then, solve it using normal algebra:
-4=3J-40
36=3J
J=12
Much easier, right?!
Hope that helps シ
