Whakaoti mō x
x=4y-2z+16
Whakaoti mō y
y=\frac{x+2z-16}{4}
Tohaina
Kua tāruatia ki te papatopenga
x+2z=16+4y
Me tāpiri te 4y ki ngā taha e rua.
x=16+4y-2z
Tangohia te 2z mai i ngā taha e rua.
-4y+2z=16-x
Tangohia te x mai i ngā taha e rua.
-4y=16-x-2z
Tangohia te 2z mai i ngā taha e rua.
-4y=16-2z-x
He hanga arowhānui tō te whārite.
\frac{-4y}{-4}=\frac{16-2z-x}{-4}
Whakawehea ngā taha e rua ki te -4.
y=\frac{16-2z-x}{-4}
Mā te whakawehe ki te -4 ka wetekia te whakareanga ki te -4.
y=\frac{x}{4}+\frac{z}{2}-4
Whakawehe 16-x-2z ki te -4.
