Tohaina
Kua tāruatia ki te papatopenga
a-3=\sqrt{7} a-3=-\sqrt{7}
Tuhia te pūtakerua o ngā taha e rua o te whārite.
a-3-\left(-3\right)=\sqrt{7}-\left(-3\right) a-3-\left(-3\right)=-\sqrt{7}-\left(-3\right)
Me tāpiri 3 ki ngā taha e rua o te whārite.
a=\sqrt{7}-\left(-3\right) a=-\sqrt{7}-\left(-3\right)
Mā te tango i te -3 i a ia ake anō ka toe ko te 0.
a=\sqrt{7}+3
Tango -3 mai i \sqrt{7}.
a=3-\sqrt{7}
Tango -3 mai i -\sqrt{7}.
a=\sqrt{7}+3 a=3-\sqrt{7}
Kua oti te whārite te whakatau.
