Considering the given system of equations, it is found that:
A system of equations is when two or more variables are related, and equations are built to find the values of each variable.
In this problem, the system is:
-8x+y=-6
3x-2y=-1
In matrix form, it is given by:
To find the matrix |Ay|, we replace the y coefficients of 1 and -2 by the results of -6 and -1, hence:

<h3><u>Answer:</u></h3>
- 11. 6 + n = 20
- 12. n - 7 = 20
- 13. n + n + 1 = 31
- 14. 2n + 2 = 13
- 15. n - 1 = 18
- 16. n² + 4 = 2x
- 17. 2n = 1/2
- 18. n²/2 = 18
- 19. n/2 + 90/2 = 70
- 20. 2 + n = 12
