Solution:
1. Given system of equations:
*4x - 5y = 9
*-8x + 10y = 18
2. Choose a method to solve the system. Here, we will use the elimination method:
* Multiply the first equation by 2 to match the coefficients ofx
(4x - 5y = 9) \times 2 \Rightarrow 8x - 10y = 18
3. Now add this equation to the second equation to eliminatex
8x - 10y = 18
-8x + 10y = 18
----------------------------------------
0 = 36
4. The equation0 = 36
Therefore, the system of equations is inconsistent.
