3x+3z=90.9-3y
Tangohia te 3y mai i ngā taha e rua.
3x=90.9-3y-3z
Tangohia te 3z mai i ngā taha e rua.
3x=90.9-3z-3y
He hanga arowhānui tō te whārite.
\frac{3x}{3}=\frac{90.9-3z-3y}{3}
Whakawehea ngā taha e rua ki te 3.
x=\frac{90.9-3z-3y}{3}
Mā te whakawehe ki te 3 ka wetekia te whakareanga ki te 3.
x=\frac{303}{10}-z-y
Whakawehe 90.9-3y-3z ki te 3.
3y+3z=90.9-3x
Tangohia te 3x mai i ngā taha e rua.
3y=90.9-3x-3z
Tangohia te 3z mai i ngā taha e rua.
3y=90.9-3z-3x
He hanga arowhānui tō te whārite.
\frac{3y}{3}=\frac{90.9-3z-3x}{3}
Whakawehea ngā taha e rua ki te 3.
