Exercise 2.2.5

Answers

$6 x + 4 y$ is 2 times $3 x + 2 y$ . There is no solution unless the right side is $2 \cdot 10 = 20$ . Then all the points on the line $3 x + 2 y = 10$ are solutions, including $(0, 5)$ and $(4, - 1)$ . The two lines in the row picture are the same line, containing all solutions.
