Solution
The image contains a system of inequalities and matrix expressions involving and . Based on the text, I see the following:
-
Inequality:
-
Matrix equation:
We can solve this system step by step:
Step 1: Solve the matrix equation
From the matrix equation:
Solve each equation:
-
For , subtract 2 from both sides:
-
For , subtract 5 from both sides:
Step 2: Check inequality
Substitute and into the inequality: This simplifies to: This inequality is false, meaning the solution does not satisfy the inequality.
Thus, the system does not have a valid solution that satisfies both the matrix equation and the inequality.
Would you like more details or further assistance?
