x-75-\left(-75\right)=15\sqrt{21}i-\left(-75\right) x-75-\left(-75\right)=-15\sqrt{21}i-\left(-75\right)
Tambahkan 75 pada kedua-dua belah persamaan.
x=15\sqrt{21}i-\left(-75\right) x=-15\sqrt{21}i-\left(-75\right)
Menolak -75 daripada dirinya sendiri menjadikannya 0.
x=75+15\sqrt{21}i
Tolak -75 daripada 15i\sqrt{21}.
x=-15\sqrt{21}i+75
Tolak -75 daripada -15i\sqrt{21}.
x=75+15\sqrt{21}i x=-15\sqrt{21}i+75
Persamaan kini diselesaikan.
