Whakaoti mō x
x=-3y+4z-7
Whakaoti mō y
y=\frac{-x+4z-7}{3}
Tohaina
Kua tāruatia ki te papatopenga
x-4z=-7-3y
Tangohia te 3y mai i ngā taha e rua.
x=-7-3y+4z
Me tāpiri te 4z ki ngā taha e rua.
3y-4z=-7-x
Tangohia te x mai i ngā taha e rua.
3y=-7-x+4z
Me tāpiri te 4z ki ngā taha e rua.
3y=-x+4z-7
He hanga arowhānui tō te whārite.
\frac{3y}{3}=\frac{-x+4z-7}{3}
Whakawehea ngā taha e rua ki te 3.
y=\frac{-x+4z-7}{3}
Mā te whakawehe ki te 3 ka wetekia te whakareanga ki te 3.
