<PRE><B>Question 1117197</B>
 Find the value of k which matrix is 
2   - 10    -1
1    2k+3  1 
4     3    2          =75 
------
2*2k+3*2 + 1*3*-1 + 4*1*-10 - [-1*(2k+3)*4 + 1*3*2 + 2*1*-10]
-------
= 8k+12 -3 -40 - [-8k-12 +6 - 20]
-------
= 8k-31 - [-8k-26]
------
16k -5 = 75
16k = 80
k = 5
------
