The trick to any equation like this one is to get the numbers on one side and the term with an unknown on the other side. That way, your last step is to divide by the number in front of the letter into a number on the other side.
Solution
2 = - 8 - x Add 8 to both sides
2 + 8 = -8 + 8 - x Combine
10 = - x The number in front of x is - 1. Divide.
10/-1 = -x/-1
-10 =x
The letter usually has to be expressed as a number greater than 0. In other words x is positive for this question
