Homework Help: Math

4(j)-7=9


Add 7 to both sides of the equation and you get
4 j = 16
Now divide both sides of the equation by 4 and you will find out what the value of j is.

Whenever you perform the same mathematical operation on both sides of an equation, you end up with another equation that is valid.
