Answer:
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. :)
