xf=4x-3
He hanga arowhānui tō te whārite.
\frac{xf}{x}=\frac{4x-3}{x}
Whakawehea ngā taha e rua ki te x.
f=\frac{4x-3}{x}
Mā te whakawehe ki te x ka wetekia te whakareanga ki te x.
f=4-\frac{3}{x}
Whakawehe 4x-3 ki te x.
fx-4x=-3
Tangohia te 4x mai i ngā taha e rua.
\left(f-4\right)x=-3
Pahekotia ngā kīanga tau katoa e whai ana i te x.
\frac{\left(f-4\right)x}{f-4}=-\frac{3}{f-4}
Whakawehea ngā taha e rua ki te f-4.
x=-\frac{3}{f-4}
Mā te whakawehe ki te f-4 ka wetekia te whakareanga ki te f-4.
