Kua tāruatia ki te papatopenga
2z=3z+10t
Me whakarea ngā taha e rua o te whārite ki te 10, arā, te tauraro pātahi he tino iti rawa te kitea o 5,10.
3z+10t=2z
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
10t=2z-3z
Tangohia te 3z mai i ngā taha e rua.
10t=-z
Pahekotia te 2z me -3z, ka -z.
\frac{10t}{10}=-\frac{z}{10}
Whakawehea ngā taha e rua ki te 10.
t=-\frac{z}{10}
Mā te whakawehe ki te 10 ka wetekia te whakareanga ki te 10.
2z=3z+10t
Me whakarea ngā taha e rua o te whārite ki te 10, arā, te tauraro pātahi he tino iti rawa te kitea o 5,10.
2z-3z=10t
Tangohia te 3z mai i ngā taha e rua.
-z=10t
Pahekotia te 2z me -3z, ka -z.
\frac{-z}{-1}=\frac{10t}{-1}
Whakawehea ngā taha e rua ki te -1.
z=\frac{10t}{-1}
Mā te whakawehe ki te -1 ka wetekia te whakareanga ki te -1.
z=-10t
Whakawehe 10t ki te -1.
