Tohaina
Kua tāruatia ki te papatopenga
2x+z=23-3y
Tangohia te 3y mai i ngā taha e rua.
2x=23-3y-z
Tangohia te z mai i ngā taha e rua.
2x=23-z-3y
He hanga arowhānui tō te whārite.
\frac{2x}{2}=\frac{23-z-3y}{2}
Whakawehea ngā taha e rua ki te 2.
x=\frac{23-z-3y}{2}
Mā te whakawehe ki te 2 ka wetekia te whakareanga ki te 2.
3y+z=23-2x
Tangohia te 2x mai i ngā taha e rua.
3y=23-2x-z
Tangohia te z mai i ngā taha e rua.
3y=23-z-2x
He hanga arowhānui tō te whārite.
\frac{3y}{3}=\frac{23-z-2x}{3}
Whakawehea ngā taha e rua ki te 3.
y=\frac{23-z-2x}{3}
Mā te whakawehe ki te 3 ka wetekia te whakareanga ki te 3.
