Whakaoti mō y
y=x-2z-7
Whakaoti mō x
x=y+2z+7
Tohaina
Kua tāruatia ki te papatopenga
-y=2z+7-x
Tangohia te x mai i ngā taha e rua.
-y=7+2z-x
He hanga arowhānui tō te whārite.
\frac{-y}{-1}=\frac{7+2z-x}{-1}
Whakawehea ngā taha e rua ki te -1.
y=\frac{7+2z-x}{-1}
Mā te whakawehe ki te -1 ka wetekia te whakareanga ki te -1.
y=x-2z-7
Whakawehe 2z+7-x ki te -1.
x=2z+7+y
Me tāpiri te y ki ngā taha e rua.
