Kua tāruatia ki te papatopenga
2x+1=x\times 2+x
Tē taea kia ōrite te tāupe x ki 0 nā te kore tautuhi i te whakawehenga mā te kore. Whakareatia ngā taha e rua o te whārite ki te x.
2x+1=3x
Pahekotia te x\times 2 me x, ka 3x.
2x+1-3x=0
Tangohia te 3x mai i ngā taha e rua.
-x+1=0
Pahekotia te 2x me -3x, ka -x.
-x=-1
Tangohia te 1 mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
x=1
Me whakarea ngā taha e rua ki te -1.
Ngā Tauira
whārite tapawhā
{ x } ^ { 2 } - 4 x - 5 = 0
Āhuahanga
4 \sin \theta \cos \theta = 2 \sin \theta
whārite paerangi
y = 3x + 4
