Answer:

  • I₁ ≈ 0.1036∠68.75°
  • I₂ ≈ 0.1637∠50.31°

Explanation:

You want the solution in polar form of the system of equations ...

  • (2+j6)I₁ -j4·I₂ = 0
  • j·I₁ +(8-j10)I₂ = 2

The usual solution methods for a system of equations apply. The attached calculator shows the currents to be ...

  • I₁ ≈ 0.1036∠68.75°
  • I₂ ≈ 0.1637∠50.31°

Additional comment

For systems of equations in which the coefficients don't lend themselves to elimination or substitution methods, we prefer matrix methods to find a solution. A suitable calculator makes this relatively easy.
