The answer is below
Step-by-step explanation:
The system of equations:
8x-9y+13z=11
-8x-5y+5z=15
3x+4y-8z=-10
The equations can be represented in matrix form as:
AX = B
X = A⁻¹B
Therefore:
For this case we have the following expression:
We take common factor , for this we must take into account that:
So, factoring the expression we have:
ANswer:
The factored expression is:
