Kua tāruatia ki te papatopenga
\sqrt{y}-7-\left(-7\right)=-\left(-7\right)
Me tāpiri 7 ki ngā taha e rua o te whārite.
\sqrt{y}=-\left(-7\right)
Mā te tango i te -7 i a ia ake anō ka toe ko te 0.
\sqrt{y}=7
Tango -7 mai i 0.
y=49
Pūruatia ngā taha e rua o te whārite.
Ngā Tauira
whārite tapawhā
{ x } ^ { 2 } - 4 x - 5 = 0
Āhuahanga
4 \sin \theta \cos \theta = 2 \sin \theta
whārite paerangi
y = 3x + 4
