Kua tāruatia ki te papatopenga
20xy=5
Whakareatia te 4 ki te 5, ka 20.
20yx=5
He hanga arowhānui tō te whārite.
\frac{20yx}{20y}=\frac{5}{20y}
Whakawehea ngā taha e rua ki te 20y.
x=\frac{5}{20y}
Mā te whakawehe ki te 20y ka wetekia te whakareanga ki te 20y.
x=\frac{1}{4y}
Whakawehe 5 ki te 20y.
Ngā Tauira
whārite tapawhā
{ x } ^ { 2 } - 4 x - 5 = 0
Āhuahanga
