Kua tāruatia ki te papatopenga
5\times 4=4x
Me whakarea ngā taha e rua o te whārite ki te 600, arā, te tauraro pātahi he tino iti rawa te kitea o 120,150.
20=4x
Whakareatia te 5 ki te 4, ka 20.
4x=20
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
x=\frac{20}{4}
Whakawehea ngā taha e rua ki te 4.
x=5
Whakawehea te 20 ki te 4, kia riro ko 5.
Ngā Tauira
whārite tapawhā
{ x } ^ { 2 } - 4 x - 5 = 0
Āhuahanga
4 \sin \theta \cos \theta = 2 \sin \theta
