Kua tāruatia ki te papatopenga
5xy+y\left(-9\right)=1
Whakareatia ngā taha e rua o te whārite ki te y.
5xy=1-y\left(-9\right)
Tangohia te y\left(-9\right) mai i ngā taha e rua.
5xy=1+9y
Whakareatia te -1 ki te -9, ka 9.
5yx=9y+1
He hanga arowhānui tō te whārite.
\frac{5yx}{5y}=\frac{9y+1}{5y}
Whakawehea ngā taha e rua ki te 5y.
x=\frac{9y+1}{5y}
Mā te whakawehe ki te 5y ka wetekia te whakareanga ki te 5y.
x=\frac{9}{5}+\frac{1}{5y}
Whakawehe 1+9y ki te 5y.
5xy+y\left(-9\right)=1
Tē taea kia ōrite te tāupe y ki 0 nā te kore tautuhi i te whakawehenga mā te kore. Whakareatia ngā taha e rua o te whārite ki te y.
\left(5x-9\right)y=1
Pahekotia ngā kīanga tau katoa e whai ana i te y.
\frac{\left(5x-9\right)y}{5x-9}=\frac{1}{5x-9}
Whakawehea ngā taha e rua ki te 5x-9.
y=\frac{1}{5x-9}
Mā te whakawehe ki te 5x-9 ka wetekia te whakareanga ki te 5x-9.
y=\frac{1}{5x-9}\text{, }y\neq 0
Tē taea kia ōrite te tāupe y ki 0.
