Question

Help plzzzzz its hard

Answer 1

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. :)

Answer 2

Answer:

J=8

Step-by-step explanation:

Multiply parentheses by -3 5J - 3 (- 7 + 2J) =13

Collect like terms 5J + 21 - 6J =13

Move constant to the right  - J + 21 =13

Calculate - J = 13 - 21

Change the signs - J = - 8

J = 8
