Applying KVL to Mesh 1,
12−12I1−10(I1−I2)−1(I1−I3)=013I1−10I2−I3=12........................(1)
Applying KVL to Mesh 2,
−10(I2−I1)−10−2I2−3(I2−I3)=0−10I1+15I2−3I3=0..........................(2)
Applying KVL to Mesh 3,
1(I3−I1)−3(I3−I2)−4I3+24=0−I1−3I2+8I3=24.....................................(3)
Writing equations in the matrix form
[13−10−1−1015−3−1−38][I1I2I3]=[12−1024]
Solving above equations we get,
I1=2.79 A;I2=2.01 A;I3=4.1 A;I4Ω=I3=4.1 A
