KL7
iz+3(z-i)=0
eq. (i+3)z-3i=0
eq. z=3i/3+i
eq. z=3i(3-i)/(3+i)(3-i)
eq. z=3-9i/3-(-1)
eq. z=3-9i/4
eq. z=3/4+(9/4)i

(4+i)z=4-z
eq. (4+i+1)z=4
eq. (5+i)z=4
eq. z=-4/(5+i)
eq. z=4*(5-i)/(5+i)(5-i)
eq. z= (20-4i)/(5-(-1))
eq. z=10/3 -(2/3)i

Essaie de résoudre les deux restantes en t’inspirant des deux premières et je te les corrigerai.

Bon courage,
