Whakaoti mō x
x=\frac{z}{5}
Whakaoti mō z
z=5x
Tohaina
Kua tāruatia ki te papatopenga
5x=z
He hanga arowhānui tō te whārite.
\frac{5x}{5}=\frac{z}{5}
Whakawehea ngā taha e rua ki te 5.
x=\frac{z}{5}
Mā te whakawehe ki te 5 ka wetekia te whakareanga ki te 5.
z=x\times 5
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
Ngā Tauira
whārite tapawhā
{ x } ^ { 2 } - 4 x - 5 = 0
Āhuahanga
4 \sin \theta \cos \theta = 2 \sin \theta
whārite paerangi
y = 3x + 4
Arithmetic
699 * 533

Whakarerekētanga
\frac { d } { d x } \frac { ( 3 x ^ { 2 } - 2 ) } { ( x - 5 ) }
Whakaurunga
\int _ { 0 } ^ { 1 } x e ^ { - x ^ { 2 } } d x
