Whakaoti mō x
x=\frac{3y}{2}-2z+1
Whakaoti mō y

Tohaina
Kua tāruatia ki te papatopenga
2x+4z=2+3y
Me tāpiri te 3y ki ngā taha e rua.
2x=2+3y-4z
Tangohia te 4z mai i ngā taha e rua.
2x=3y-4z+2
He hanga arowhānui tō te whārite.
\frac{2x}{2}=\frac{3y-4z+2}{2}
Whakawehea ngā taha e rua ki te 2.
x=\frac{3y-4z+2}{2}
Mā te whakawehe ki te 2 ka wetekia te whakareanga ki te 2.
x=\frac{3y}{2}-2z+1
Whakawehe 2+3y-4z ki te 2.
-3y+4z=2-2x
Tangohia te 2x mai i ngā taha e rua.
-3y=2-2x-4z
Tangohia te 4z mai i ngā taha e rua.
-3y=2-4z-2x
He hanga arowhānui tō te whārite.
\frac{-3y}{-3}=\frac{2-4z-2x}{-3}
Whakawehea ngā taha e rua ki te -3.
y=\frac{2-4z-2x}{-3}
Mā te whakawehe ki te -3 ka wetekia te whakareanga ki te -3.
y=\frac{2x+4z-2}{3}
Whakawehe 2-2x-4z ki te -3.
