Loop i1
By applying Kirchhoff Voltage Law (KVL);
i1(R1 + R3) + i2R3 = + V1
The current i1 and The current i1 and
i2 flows through the current from
R3 are in the supply 12V are in
same direction the same direction
i1(4 + 1) + 1i2 = 12
5i1 + 1i2 = 12 --------------------------------- (1)

Loop i2
By applying Kirchhoff Voltage Law (KVL);
i2(R2 + R3) + i1R3 = +V2
The current i1 and i2 The current i2 and
flows through R3 are the current from
in the same direction supply 10V are in
the same direction
(2 + 1) i2 + 1i1= 10
1i1 + 3i2 = 10 --------------------------------- (2)
