Final answer:
To solve the matrix equation [x 1 x2] + [-2 5] = [8 15], we need to find the values of x1 and x2. The correct answer is x1 = 10, x2 = 5.
Step-by-step explanation:
To solve the matrix equation [x 1 x2] + [-2 5] = [8 15], we need to find the values of x1 and x2. We can rewrite the equation as a system of linear equations:
x - 2 = 8
x2 + 5 = 15
Solving the first equation, we find that x1 = 10. Substituting this value into the second equation, we find that x2 = 5. Therefore, the correct answer is x1 = 10, x2 = 5.
