Whakaoti mō h
h=2\left(r-4\right)
Tohaina
Kua tāruatia ki te papatopenga
h=2r-8
Whakamahia te āhuatanga tohatoha hei whakarea te 2 ki te r-4.
2r-8=h
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
2r=h+8
Me tāpiri te 8 ki ngā taha e rua.
\frac{2r}{2}=\frac{h+8}{2}
Whakawehea ngā taha e rua ki te 2.
r=\frac{h+8}{2}
Mā te whakawehe ki te 2 ka wetekia te whakareanga ki te 2.
r=\frac{h}{2}+4
Whakawehe h+8 ki te 2.
h=2r-8
Whakamahia te āhuatanga tohatoha hei whakarea te 2 ki te r-4.
