Kua tāruatia ki te papatopenga
2\times 2=2x-1+c
Me whakarea ngā taha e rua ki te 2.
4=2x-1+c
Whakareatia te 2 ki te 2, ka 4.
2x-1+c=4
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
-1+c=4-2x
Tangohia te 2x mai i ngā taha e rua.
c=4-2x+1
Me tāpiri te 1 ki ngā taha e rua.
c=5-2x
Tāpirihia te 4 ki te 1, ka 5.
2\times 2=2x-1+c
Me whakarea ngā taha e rua ki te 2.
4=2x-1+c
Whakareatia te 2 ki te 2, ka 4.
2x-1+c=4
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
2x+c=4+1
Me tāpiri te 1 ki ngā taha e rua.
2x+c=5
Tāpirihia te 4 ki te 1, ka 5.
2x=5-c
Tangohia te c mai i ngā taha e rua.
\frac{2x}{2}=\frac{5-c}{2}
Whakawehea ngā taha e rua ki te 2.
x=\frac{5-c}{2}
Mā te whakawehe ki te 2 ka wetekia te whakareanga ki te 2.
