There are two solar panels, A and B placed parallel to each other on the terrace of a building. The equation of the surface of the panel A is $2x + 2y - z + 9 = 0$.
A fly is sitting on panel A. The position of the fly is $(2, m, 3)$. Find the value of '$m$'.
Answer
Answer
AIThe fly lies on panel A, so $2(2) + 2m - 3 + 9 = 0$, that is $2m + 10 = 0$.
$m = -5$.
Final answer: $-5$
