Answer:
Option (c) is correct.
Explanation:
Tina wrote two equations :
3x - y = 9 ...(1)
And
4x + y + 5 = 0
4x + y = -5 ....(2)
Adding equation (1) and (2) we get :
3x - y + 4x + y = 9+5
7x = 14
x = 2
Put the value of x in equation (1)
3(2)-y=9
6-y=9
y = -3
The solution of the equation (1) and (2) is x = 2 and y = -3
Hence, the correct conclusion is "(2, –3) is a solution to the system of linear equations".
