Answer:
No
Step-by-step explanation:
Substitute x = 5, y = - 9 into the 2 equations and if the left side is equal to the right side for both equations then (5, - 9 ) is a solution
17(5) + 8(- 9) = 85 - 72 = 13 ← True
17(5) - 20(- 9) = 85 + 180 = 265 ≠ - 20
Thus (5, - 9 ) is not a solution to the system of equations
