Go to khan academy and search "basic rearrangement".

 

Oops that doesn't work..


Try this: and when you do, reply

 

What can you do to both sides of the equation in order to keep the j "alone" on one side, but still keep the equation equal?

Sidenote here for the question-asker: This method is called "isolating the variable", and it will pop up for the remainder of your schoolwork, all the way up to middle school and beyond!

It means to bring the variable on one side and to the constants on the other side essentially.

Yeah "isolate" it to one side, put it in quarantine, whatever you want to call it.

j+4=17

 

The first step get rid of the numbers

 

j=17+4

 

Simplify the right side

 

j=21
