The answer to the problem is x=17
7 times 7 = 49. Perfect square.
3 times 3 = 9. Perfect square.
15 times 15 = 225. Again, a perfect square.
The other two, 17 and 143, come out as decimals. So, your final answer would be 49, 7 and 225. Hope it helps! If you could vote my answer as the brainiest, that would be awesome! :)

Answer:
- Switch positions of two rows.
- Add elements of one row to another row.
- Multiply elements of one row by a scalar
Step-by-step explanation:
In general, each row represents a linear equation. The rules of equality apply. They allow you to multiply both sides of the equation by a scalar, add equal values to each side of the equation (add one row to another). Rearranging the sequence of equations (swapping rows) does not change the system or its solution.
