x-5-\left(-5\right)=\sqrt{11}i-\left(-5\right) x-5-\left(-5\right)=-\sqrt{11}i-\left(-5\right)
Adio 5 at ddwy ochr yr hafaliad.
x=\sqrt{11}i-\left(-5\right) x=-\sqrt{11}i-\left(-5\right)
Mae tynnu -5 o’i hun yn gadael 0.
x=5+\sqrt{11}i
Tynnu -5 o i\sqrt{11}.
x=-\sqrt{11}i+5
Tynnu -5 o -i\sqrt{11}.
x=5+\sqrt{11}i x=-\sqrt{11}i+5
