Kua tāruatia ki te papatopenga
4-kx=x
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
-kx=x-4
Tangohia te 4 mai i ngā taha e rua.
\left(-x\right)k=x-4
He hanga arowhānui tō te whārite.
\frac{\left(-x\right)k}{-x}=\frac{x-4}{-x}
Whakawehea ngā taha e rua ki te -x.
k=\frac{x-4}{-x}
Mā te whakawehe ki te -x ka wetekia te whakareanga ki te -x.
k=-1+\frac{4}{x}
Whakawehe x-4 ki te -x.
x+kx=4
Me tāpiri te kx ki ngā taha e rua.
\left(1+k\right)x=4
Pahekotia ngā kīanga tau katoa e whai ana i te x.
\left(k+1\right)x=4
He hanga arowhānui tō te whārite.
\frac{\left(k+1\right)x}{k+1}=\frac{4}{k+1}
Whakawehea ngā taha e rua ki te 1+k.
x=\frac{4}{k+1}
Mā te whakawehe ki te 1+k ka wetekia te whakareanga ki te 1+k.
