It's quite difficult, almost impossible to write all steps to solve a 3x3 matrix.
However, I will give you te answer that is determinant (Matrix)=54
Add 9 to both sides
So
33=2x
Divide both sides by 2
So
X=16.5
L = 4D + 54 <== ur equation
the crew worked for 31 days...so sub in 31 for D
L = 4(31) + 54
L = 124 + 54
L = 178 miles <==
