Whakaoti mō x
x=\frac{10y-10z}{13}
Whakaoti mō y
y=\frac{13x}{10}+z

Kua tāruatia ki te papatopenga
1.3x+z=y
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
1.3x=y-z
Tangohia te z mai i ngā taha e rua.
\frac{1.3x}{1.3}=\frac{y-z}{1.3}
Whakawehea ngā taha e rua o te whārite ki te 1.3, he ōrite ki te whakarea i ngā taha e rua ki te tau huripoki o te hautanga.
x=\frac{y-z}{1.3}
Mā te whakawehe ki te 1.3 ka wetekia te whakareanga ki te 1.3.
x=\frac{10y-10z}{13}
Whakawehe y-z ki te 1.3 mā te whakarea y-z ki te tau huripoki o 1.3.
