Kua tāruatia ki te papatopenga
y\left(x-3\right)=-2+\left(x-3\right)\left(-4\right)
Tē taea kia ōrite te tāupe x ki 3 nā te kore tautuhi i te whakawehenga mā te kore. Whakareatia ngā taha e rua o te whārite ki te x-3.
yx-3y=-2+\left(x-3\right)\left(-4\right)
Whakamahia te āhuatanga tohatoha hei whakarea te y ki te x-3.
yx-3y=-2-4x+12
Whakamahia te āhuatanga tohatoha hei whakarea te x-3 ki te -4.
yx-3y=10-4x
Tāpirihia te -2 ki te 12, ka 10.
yx-3y+4x=10
Me tāpiri te 4x ki ngā taha e rua.
yx+4x=10+3y
Me tāpiri te 3y ki ngā taha e rua.
\left(y+4\right)x=10+3y
Pahekotia ngā kīanga tau katoa e whai ana i te x.
\left(y+4\right)x=3y+10
He hanga arowhānui tō te whārite.
\frac{\left(y+4\right)x}{y+4}=\frac{3y+10}{y+4}
Whakawehea ngā taha e rua ki te y+4.
x=\frac{3y+10}{y+4}
Mā te whakawehe ki te y+4 ka wetekia te whakareanga ki te y+4.
x=\frac{3y+10}{y+4}\text{, }x\neq 3
Tē taea kia ōrite te tāupe x ki 3.
