Kua tāruatia ki te papatopenga
x\left(y-1\right)=-1+\left(y-1\right)\times 3
Tē taea kia ōrite te tāupe y ki 1 nā te kore tautuhi i te whakawehenga mā te kore. Whakareatia ngā taha e rua o te whārite ki te y-1.
xy-x=-1+\left(y-1\right)\times 3
Whakamahia te āhuatanga tohatoha hei whakarea te x ki te y-1.
xy-x=-1+3y-3
Whakamahia te āhuatanga tohatoha hei whakarea te y-1 ki te 3.
xy-x=-4+3y
Tangohia te 3 i te -1, ka -4.
xy-x-3y=-4
Tangohia te 3y mai i ngā taha e rua.
xy-3y=-4+x
Me tāpiri te x ki ngā taha e rua.
\left(x-3\right)y=-4+x
Pahekotia ngā kīanga tau katoa e whai ana i te y.
\left(x-3\right)y=x-4
He hanga arowhānui tō te whārite.
\frac{\left(x-3\right)y}{x-3}=\frac{x-4}{x-3}
Whakawehea ngā taha e rua ki te x-3.
y=\frac{x-4}{x-3}
Mā te whakawehe ki te x-3 ka wetekia te whakareanga ki te x-3.
y=\frac{x-4}{x-3}\text{, }y\neq 1
Tē taea kia ōrite te tāupe y ki 1.
