Kua tāruatia ki te papatopenga
9x=7+5y
Me tāpiri te 5y ki ngā taha e rua.
9x=5y+7
He hanga arowhānui tō te whārite.
\frac{9x}{9}=\frac{5y+7}{9}
Whakawehea ngā taha e rua ki te 9.
x=\frac{5y+7}{9}
Mā te whakawehe ki te 9 ka wetekia te whakareanga ki te 9.
-5y=7-9x
Tangohia te 9x mai i ngā taha e rua.
\frac{-5y}{-5}=\frac{7-9x}{-5}
Whakawehea ngā taha e rua ki te -5.
y=\frac{7-9x}{-5}
Mā te whakawehe ki te -5 ka wetekia te whakareanga ki te -5.
y=\frac{9x-7}{5}
Whakawehe 7-9x ki te -5.
