Tohaina
Kua tāruatia ki te papatopenga
2x-8=0
Whakaarohia te whārite tuatahi. Pahekotia te 4x me -2x, ka 2x.
2x=8
Me tāpiri te 8 ki ngā taha e rua. Ko te tau i tāpiria he kore ka hua koia tonu.
x=\frac{8}{2}
Whakawehea ngā taha e rua ki te 2.
x=4
Whakawehea te 8 ki te 2, kia riro ko 4.
x=4 y=-2 z=-2 a=-2 b=-2
Kua oti te pūnaha te whakatau.
Ngā Tauira
whārite tapawhā
{ x } ^ { 2 } - 4 x - 5 = 0
Āhuahanga
4 \sin \theta \cos \theta = 2 \sin \theta
whārite paerangi
y = 3x + 4
