H=5-2x-4
Hei kimi i te tauaro o 2x+4, kimihia te tauaro o ia taurangi.
H=1-2x
Tangohia te 4 i te 5, ka 1.
H=5-2x-4
Hei kimi i te tauaro o 2x+4, kimihia te tauaro o ia taurangi.
H=1-2x
Tangohia te 4 i te 5, ka 1.
1-2x=H
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
-2x=H-1
Tangohia te 1 mai i ngā taha e rua.
\frac{-2x}{-2}=\frac{H-1}{-2}
Whakawehea ngā taha e rua ki te -2.
x=\frac{H-1}{-2}
Mā te whakawehe ki te -2 ka wetekia te whakareanga ki te -2.
x=\frac{1-H}{2}
Whakawehe H-1 ki te -2.
