Help plz its hard

J = 8

Step-by-step explanation:

First we start with what is given:

5J - 3(-7 + 2J) = 13

We have to first distribute the -3 to the numbers in the parentheses.

We now have:

5J + 21 - 6J = 13

Now, combine like terms:

-J = -8

Of course, the J (or variable) cannot be negative. Remember, whatever we do to one side of the equal side, we MUST do to the other. So, if we remove the negative sign from the -J, we remove it from the -8 too.

J = 8

Now we are done! I hope this helps you. :)
