Tohaina
Kua tāruatia ki te papatopenga
-13y=-24-20z
Tangohia te 20z mai i ngā taha e rua.
-13y=-20z-24
He hanga arowhānui tō te whārite.
\frac{-13y}{-13}=\frac{-20z-24}{-13}
Whakawehea ngā taha e rua ki te -13.
y=\frac{-20z-24}{-13}
Mā te whakawehe ki te -13 ka wetekia te whakareanga ki te -13.
y=\frac{20z+24}{13}
Whakawehe -24-20z ki te -13.
20z=-24+13y
Me tāpiri te 13y ki ngā taha e rua.
20z=13y-24
He hanga arowhānui tō te whārite.
\frac{20z}{20}=\frac{13y-24}{20}
Whakawehea ngā taha e rua ki te 20.
z=\frac{13y-24}{20}
Mā te whakawehe ki te 20 ka wetekia te whakareanga ki te 20.
z=\frac{13y}{20}-\frac{6}{5}
Whakawehe -24+13y ki te 20.
