Okay, let me help break this down for you. In this equation as we call it, we need to ISOLATE the "x" value which means to have be by itself in order to solve the equation.
So we have 2 + 8 - x = -24
Lets start with the 2. We will Subtract it over in order to get 8 - x = - 26
Next lets subtract over the 8. We will then end up with -x = - 34
Now we get rid of the negatives by dividing each side by a negative 1 (remember -x is the same as -1x). After this we will have got our answer
