Kua tāruatia ki te papatopenga
2x+9yz=2
Whakareatia te 3 ki te 3, ka 9.
9yz=2-2x
Tangohia te 2x mai i ngā taha e rua.
9zy=2-2x
He hanga arowhānui tō te whārite.
\frac{9zy}{9z}=\frac{2-2x}{9z}
Whakawehea ngā taha e rua ki te 9z.
y=\frac{2-2x}{9z}
Mā te whakawehe ki te 9z ka wetekia te whakareanga ki te 9z.
y=\frac{2\left(1-x\right)}{9z}
Whakawehe 2-2x ki te 9z.
