1. Multiply the first equation by 1:
x - 2y = 17

2. Multiply the second equation by 2:
6x - 2y = 62

3. Subtract the first equation from the modified second equation:
6x - 2y - (x - 2y) = 62 - 17
5x = 45
x = 9

4. Substitute \( x = 9 \) back into the first equation:
9 - 2y = 17
-2y = 8
y = -4

Answer:
x = 9, \; y = -4
