Kua tāruatia ki te papatopenga
7x-2=0
Pahekotia te 3x me 4x, ka 7x.
7x=2
Me tāpiri te 2 ki ngā taha e rua. Ko te tau i tāpiria he kore ka hua koia tonu.
x=\frac{2}{7}
Whakawehea ngā taha e rua ki te 7.
Ngā Tauira
whārite tapawhā
{ x } ^ { 2 } - 4 x - 5 = 0
Āhuahanga
4 \sin \theta \cos \theta = 2 \sin \theta
whārite paerangi
