Tohaina
Kua tāruatia ki te papatopenga
3x-y=7-x^{2}
Tangohia te x^{2} mai i ngā taha e rua.
-y=7-x^{2}-3x
Tangohia te 3x mai i ngā taha e rua.
-y=7-3x-x^{2}
He hanga arowhānui tō te whārite.
\frac{-y}{-1}=\frac{7-3x-x^{2}}{-1}
Whakawehea ngā taha e rua ki te -1.
y=\frac{7-3x-x^{2}}{-1}
Mā te whakawehe ki te -1 ka wetekia te whakareanga ki te -1.
y=x^{2}+3x-7
Whakawehe 7-x^{2}-3x ki te -1.
