Answer 1

To find the solution for the system of equations using Jian's table, we can look for the pair of x- and y-values where the outputs from both equations are the same.

From the table we have:

For the equation \(y = 2x - 5\):
- At \(x = 0\), \(y = -5\)
- At \(x = 1\), \(y = -3\)
- At \(x = 2\), \(y = -1\)
- At \(x = 3\), \(y = 1\)

For the equation \(y = x - 3\):
- At \(x = 0\), \(y = -3\)
- At \(x = 1\), \(y = -2\)
- At \(x = 2\), \(y = -1\)
- At \(x = 3\), \(y = 0\)

Now, let's look for the x-value where the y-values from both equations are equal:

1. **At \(x = 0\)**:
- \(y = 2(0) - 5 = -5\)
- \(y = 0 - 3 = -3\)

2. **At \(x = 1\)**:
- \(y = 2(1) - 5 = -3\)
- \(y = 1 - 3 = -2\)

3. **At \(x = 2\)**:
- \(y = 2(2) - 5 = -1\)
- \(y = 2 - 3 = -1\) (same value)

4. **At \(x = 3\)**:
- \(y = 2(3) - 5 = 1\)
- \(y = 3 - 3 = 0\)

The only point where the y-values from both equations are equal is \( (2, -1) \).

Thus, the solution to the system of equations is:

**(2, −1)**.
