The determinant is C. -541.
Using a cofactor expansion along the first row:

Question 2
<span> 2(2x − 5 − 4) = 160 − 17
4x-10-8 = 160-17
4x-18=143
4x = 161
x=40.25
</span>
Question 3
<span>4(2z + 3) = 12
8z +12 = 12
8z = 0
z = 0
</span><span>Question 4
</span>
<span>5(2x − 6) + 20 = 10
10x-30+20=10
10x-10=10
10x =20
x=2
</span>
<span>Question 5
</span>
<span>5x + 10 = 5x − 8
5x+18=5x
18=0
Zero solutions
