What is the first step to solving this equation? 8 + 9x = -6

In order to solve this equation you must isolate your values.

So the first step would to get all the single values to one designated side.

·Tip: it is easier if you just leave X alone all together.

So if we are leaving X alone, the only way we could isolate the X is if we subtract 8 from the left side and add it to the right side.

·8+9x=-6
 -8   ⇒  +8

Now when we add and subtract the given values .

·9x=2

Then in order to solve for X we would devide both sides by the quantity of X

·9x=2

     9

The we get 

·X=.222
