Hi Vincen,

We're told that X and Y are integers, and 4X + 5Y = 19. We're asked which of the following COULD be the value of X.

This question is perfect for TESTing THE ANSWERS - one of those numbers MUST be a solution to the given equation (note: we're told that BOTH variables are INTEGERS, so when you TEST a value for X, the corresponding value of Y must also be an integer). When you plug-in a value of X and find the corresponding Y or plug in the Y and find the corresponding value for X, the equation is relatively "small", so it shouldn't take too long to do the basic arithmetic and find the solution.

Final Answer: A
