Graph
Tohaina
Kua tāruatia ki te papatopenga
3x=-15+15y
Me tāpiri te 15y ki ngā taha e rua.
3x=15y-15
He hanga arowhānui tō te whārite.
\frac{3x}{3}=\frac{15y-15}{3}
Whakawehea ngā taha e rua ki te 3.
x=\frac{15y-15}{3}
Mā te whakawehe ki te 3 ka wetekia te whakareanga ki te 3.
x=5y-5
Whakawehe -15+15y ki te 3.
Ngā Tauira
whārite tapawhā
{ x } ^ { 2 } - 4 x - 5 = 0
Āhuahanga
