Agree, thanks @Dipen.

Using mesh law.

As we have two mesh,
from first mesh:
68(I1)+37(I1-I2)=12,
from 2nd mesh,
90(I2)+37(I2-I1)=-4,
Solving these two we get;
I1=0.1149Am.
I2=2mA.

How to solve this? Please tell me clearly.

See they give mesh current but you solved nodal method how it's possible?

Thanks @Dilip.

I solve the equation and the IR1 = 0.315 is that right?

Please explain it.

Nodal equation.

For I1.

68I1+ (I1-I2) 37= 12V.

F0r I2.

90I2 + (I2-I1) 37= 4.

Solve these two equation simultaneously.

Nodal eqn=>((va-12)/68)+(va/37)+((Va-4)/90)=0
Va=4.180volt
Ir1=((12-Va)/68)
= (12-4.18)/68
=115mA
