Answer

Eliminate y from the new equations to find the value of k: $k = \frac{- 2 x + 16 y + z - 2}{z}$

Steps

Step 1 ：Eliminate x from the first two equations and then from the second and third equations to get two new equations: $5 y - 2 z = - 1$ and $2 x - 6 y - z (4 - k) - z = - 4$

Step 2 ：Eliminate y from the new equations to find the value of k: $k = \frac{- 2 x + 16 y + z - 2}{z}$

x+2y−3z=2x−3y−z=3−x+3y+(4−k)z=7If we don't apply the Cramer's method to the given linear system then find the value for k.
