Tohaina
Kua tāruatia ki te papatopenga
18x-5z=8-2y
Tangohia te 2y mai i ngā taha e rua.
18x=8-2y+5z
Me tāpiri te 5z ki ngā taha e rua.
18x=8+5z-2y
He hanga arowhānui tō te whārite.
\frac{18x}{18}=\frac{8+5z-2y}{18}
Whakawehea ngā taha e rua ki te 18.
x=\frac{8+5z-2y}{18}
Mā te whakawehe ki te 18 ka wetekia te whakareanga ki te 18.
x=\frac{5z}{18}-\frac{y}{9}+\frac{4}{9}
Whakawehe 8-2y+5z ki te 18.
2y-5z=8-18x
Tangohia te 18x mai i ngā taha e rua.
2y=8-18x+5z
Me tāpiri te 5z ki ngā taha e rua.
2y=8+5z-18x
He hanga arowhānui tō te whārite.
\frac{2y}{2}=\frac{8+5z-18x}{2}
Whakawehea ngā taha e rua ki te 2.
y=\frac{8+5z-18x}{2}
Mā te whakawehe ki te 2 ka wetekia te whakareanga ki te 2.
y=\frac{5z}{2}-9x+4
Whakawehe 8-18x+5z ki te 2.
