Answer:
D. (–3, 5) satisfies both the equation 6x + 5y = 7 and the equation x + 4y = 17.
Explanation:
The given equations are:

and

Betty correctly determined that the ordered pair
is a solution by substituting it into both equations.
Betty's work will look like this;
First Equation:


This statement is True.
Second equation;


This is also TRUE
Hence the correct answer is
D. (–3, 5) satisfies both the equation 6x + 5y = 7 and the equation x + 4y = 17.
