Kua tāruatia ki te papatopenga
3fx=1-2x
Whakareatia ngā taha e rua o te whārite ki te 3.
3xf=1-2x
He hanga arowhānui tō te whārite.
\frac{3xf}{3x}=\frac{1-2x}{3x}
Whakawehea ngā taha e rua ki te 3x.
f=\frac{1-2x}{3x}
Mā te whakawehe ki te 3x ka wetekia te whakareanga ki te 3x.
f=-\frac{2}{3}+\frac{1}{3x}
Whakawehe 1-2x ki te 3x.
3fx=1-2x
Whakareatia ngā taha e rua o te whārite ki te 3.
3fx+2x=1
Me tāpiri te 2x ki ngā taha e rua.
\left(3f+2\right)x=1
Pahekotia ngā kīanga tau katoa e whai ana i te x.
\frac{\left(3f+2\right)x}{3f+2}=\frac{1}{3f+2}
Whakawehea ngā taha e rua ki te 3f+2.
x=\frac{1}{3f+2}
Mā te whakawehe ki te 3f+2 ka wetekia te whakareanga ki te 3f+2.
