Question 144717: Solve the system of equations using the addition (elimination) method.
If the answer is a unique solution, present it as an ordered pair: (x, y). If not, specify whether the answer is "no solution" or "infinitely many solutions."
2x – 7y = 3
-4x + 14y = -9

Multiply the first equation by -2 to get
Now you have two equations with identical coefficients on x and y but with a different constant term, therefore, no solution. (identical coefficients AND equal constant terms is 'infinitely many solutions')
