# Tina's System of Linear Equations

## Explanation:

**Tina wrote two equations:**

- 3x - y = 9 ...(1)
- 4x + y + 5 = 0

Adding equation (1) and (2) we get:

3x - y + 4x + y = 9 + 5

7x = 14

x = 2

Putting the value of x in equation (1), we get:

3(2) - y = 9

6 - y = 9

y = -3

Therefore, the solution to the equations is x = 2 and y = -3. Hence, Tina's correct conclusion is that "(2, -3) is a solution to the system of linear equations."
