Kua tāruatia ki te papatopenga
x\times 2+2=x\times 3-3
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.
x\times 2+2-x\times 3=-3
Tangohia te x\times 3 mai i ngā taha e rua.
-x+2=-3
Pahekotia te x\times 2 me -x\times 3, ka -x.
-x=-3-2
Tangohia te 2 mai i ngā taha e rua.
-x=-5
Tangohia te 2 i te -3, ka -5.
x=5
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

Whakarerekētanga
\frac { d } { d x } \frac { ( 3 x ^ { 2 } - 2 ) } { ( x - 5 ) }
Whakaurunga
