Step-by-step explanation:
To determine if the point (- 3, 5) is a solution to both equations.
Substitute the x and y values into the left side of both equations and if equal to the right sides then the point is a solution.
x - 3y = - 3 - 3(5) = - 3 - 15 = - 18 ← True
- 2x + y = - 2(- 3) + 5 = 6 + 5 = 11 ← False
Thus (- 3, 5) is not a solution to the system of equations.
