1000x+200z=9300-500y
Tangohia te 500y mai i ngā taha e rua.
1000x=9300-500y-200z
Tangohia te 200z mai i ngā taha e rua.
1000x=9300-200z-500y
He hanga arowhānui tō te whārite.
\frac{1000x}{1000}=\frac{9300-200z-500y}{1000}
Whakawehea ngā taha e rua ki te 1000.
x=\frac{9300-200z-500y}{1000}
Mā te whakawehe ki te 1000 ka wetekia te whakareanga ki te 1000.
x=-\frac{y}{2}-\frac{z}{5}+\frac{93}{10}
Whakawehe 9300-500y-200z ki te 1000.
500y+200z=9300-1000x
Tangohia te 1000x mai i ngā taha e rua.
500y=9300-1000x-200z
Tangohia te 200z mai i ngā taha e rua.
500y=9300-200z-1000x
He hanga arowhānui tō te whārite.
\frac{500y}{500}=\frac{9300-200z-1000x}{500}
Whakawehea ngā taha e rua ki te 500.
y=\frac{9300-200z-1000x}{500}
Mā te whakawehe ki te 500 ka wetekia te whakareanga ki te 500.
y=-\frac{2z}{5}-2x+\frac{93}{5}
Whakawehe 9300-1000x-200z ki te 500.
