Whakaoti mō x
x=2-3z-2y
Whakaoti mō y
y=-\frac{x}{2}-\frac{3z}{2}+1
Tohaina
Kua tāruatia ki te papatopenga
x+3z=2-2y
Tangohia te 2y mai i ngā taha e rua.
x=2-2y-3z
Tangohia te 3z mai i ngā taha e rua.
2y+3z=2-x
Tangohia te x mai i ngā taha e rua.
2y=2-x-3z
Tangohia te 3z mai i ngā taha e rua.
2y=2-3z-x
He hanga arowhānui tō te whārite.
\frac{2y}{2}=\frac{2-3z-x}{2}
Whakawehea ngā taha e rua ki te 2.
y=\frac{2-3z-x}{2}
Mā te whakawehe ki te 2 ka wetekia te whakareanga ki te 2.
y=-\frac{x}{2}-\frac{3z}{2}+1
Whakawehe 2-x-3z ki te 2.
