Problem

What is the intersection of the lines given by and ? Enter the answer as an ordered pair.
Solution
To find the intersection, we must find the point satisfying both equations. Hence we must solve the system Adding two times the second equation to the first, we get , which simplifies to . Solving for , we find that . Plugging this into the second equation above, we obtain . So the intersection is .
Final answer
\left(-\frac{5}{9}, \frac{16}{9}\right)
