Answer: $a-2b=0$

Given: $\begin{bmatrix} a+4& 3b\\ 8 & -6 \end{bmatrix}\begin{bmatrix} 2a+2& b+2\\ 8 & a-8b \end{bmatrix}=0$ find $a-2b$

Solution:

$So,\\ a+4=2 a+2\\ 2 a-a=4-2\\ a=2 \quad \ldots \ldots .(1)\\ 3 b=b+2\\ 2 b=2\\ b=1 \quad \ldots \ldots(2)\\a-2b=2-2(1)\; \; \; \; \; \; \; \; \; \; \; \; \; \; From (1)\: and(2)\\=2-2\\a-2b=0$
