Tohaina
Kua tāruatia ki te papatopenga
100x+2z=19-5y
Tangohia te 5y mai i ngā taha e rua.
100x=19-5y-2z
Tangohia te 2z mai i ngā taha e rua.
100x=19-2z-5y
He hanga arowhānui tō te whārite.
\frac{100x}{100}=\frac{19-2z-5y}{100}
Whakawehea ngā taha e rua ki te 100.
x=\frac{19-2z-5y}{100}
Mā te whakawehe ki te 100 ka wetekia te whakareanga ki te 100.
x=-\frac{y}{20}-\frac{z}{50}+\frac{19}{100}
Whakawehe 19-5y-2z ki te 100.
5y+2z=19-100x
Tangohia te 100x mai i ngā taha e rua.
5y=19-100x-2z
Tangohia te 2z mai i ngā taha e rua.
5y=19-2z-100x
He hanga arowhānui tō te whārite.
\frac{5y}{5}=\frac{19-2z-100x}{5}
Whakawehea ngā taha e rua ki te 5.
y=\frac{19-2z-100x}{5}
Mā te whakawehe ki te 5 ka wetekia te whakareanga ki te 5.
y=-\frac{2z}{5}-20x+\frac{19}{5}
Whakawehe 19-100x-2z ki te 5.
