First write the equations for the voltage drops around each loop.
For loop 1: 4X - 4Y + 15X - 15Z - 40 = 0
For loop 2: 4Y - 4X + 8Y + 10Y - 10Z = 0
For loop 3: 10Z - 10Y + Z + 15Z - 15X = 0
Combining like terms within each equation produces
19X -
4Y -
15Z = 40
-4X +
22Y -
10Z =
0
-15X -
10Y +
26Z =
0
