Question

Which is the correct coefficient matrix for this system? 3x - 4y = 12 x + 6y = 10

Answer 1

The coefficients of x and y in the first equation are 3 and -4, respectively.

The coefficients of x and y in the second equation are 1 and 6, respectively.

The coefficient matrix lists these coefficients in order on successive rows, so it will be ...

`\left[\begin{array}{cc}3&-4\\1&6\end{array}\right]`
