Answer:If you are given ordered pairs and asked if they are solutions to the equation, substitute the values in for X and Y. See if the 2 sides equal. If they do equal, then that ordered pair is a solution. If they don't equal, then the ordered pair is not a solution.

the answer is x=10 because if you subtract 8 to both sides you get 20 and then you divide by 2 and get 10
