Today we learned more about type 4 equations. (The variable is on both sides) The important thing to remember is to get the variables on one side and the numbers on the other side. Here is an example of a type 4 equation. 8y-6=5y+12. Now to solve this we need to isolate the variables, so we would add them together, but once you move the variable it becomes opposite of what it used to be. Ex 5 would be -5.
So now we have: 3y=6+12. Now we would just add the 6 and the 12. Now we have: 3y=18. The next step is to divide: 18/3=y. now we know that y=6. And you’re done.

Good explanation, BUT....when you say you're done, are you really done? Make sure you plug the answer back in to check!
