# Math Help - Augmented Matricies Problem

1. ## Augmented Matricies Problem

Can someone help me with this augmented matries question please ?

Solve the equation (using augmented matrix)

2x-3y+z=9
4x-6y+kz=m

thanks

2. $\left[\begin{array}{rrr|c}2&-3&1&9\\4&-6&k&m\end{array}\right]$

3. youll need to use elementary row operations

first id suggest switching rows 1 and 2, then multiplying the first row by the appropriate scalar as to cancle everything possible in row 2 (in this case -2) and then add row 1 to row 2, resulting in a row looking like

|0 0 x | y|
so in this case x =y, this will be different for yours
