\Delta x=20
He hanga arowhānui tō te whārite.
\frac{\Delta x}{\Delta }=\frac{20}{\Delta }
Whakawehea ngā taha e rua ki te \Delta .
x=\frac{20}{\Delta }
Mā te whakawehe ki te \Delta ka wetekia te whakareanga ki te \Delta .
x\Delta =20
He hanga arowhānui tō te whārite.
\frac{x\Delta }{x}=\frac{20}{x}
Whakawehea ngā taha e rua ki te x.
\Delta =\frac{20}{x}
Mā te whakawehe ki te x ka wetekia te whakareanga ki te x.
