Question

solve the matrix

Answer 1

If we had an equation like \(x-5=1\), how would you solve for \(x\)?

Answer 2

move -5 over to the other side of the equal side and add to the 1

Answer 3

\[\left[\begin{matrix}a & b \\ c & d\end{matrix}\right] - \left[\begin{matrix}e & f \\ g & h\end{matrix}\right] = \left[\begin{matrix}(a - e) & (b - f) \\ (c - g) & (d - h)\end{matrix}\right]\]

Answer 4

@selenamalter elaborate what you mean by 'moving' \(-5\)? Do you *add* \(5\) to both sides?

Answer 5

yes

Answer 6

okay, so im thinking it would be

Answer 7

@selenamalter use the same approach here :-) Because we're subtracting that matrix from \(x\), to get \(x\) alone, we're going to *add* it to both sides! Do you know how to add matrices?
