Kua tāruatia ki te papatopenga
9x=15+8y
Me tāpiri te 8y ki ngā taha e rua.
9x=8y+15
He hanga arowhānui tō te whārite.
\frac{9x}{9}=\frac{8y+15}{9}
Whakawehea ngā taha e rua ki te 9.
x=\frac{8y+15}{9}
Mā te whakawehe ki te 9 ka wetekia te whakareanga ki te 9.
x=\frac{8y}{9}+\frac{5}{3}
Whakawehe 15+8y ki te 9.
-8y=15-9x
Tangohia te 9x mai i ngā taha e rua.
\frac{-8y}{-8}=\frac{15-9x}{-8}
Whakawehea ngā taha e rua ki te -8.
y=\frac{15-9x}{-8}
Mā te whakawehe ki te -8 ka wetekia te whakareanga ki te -8.
y=\frac{9x-15}{8}
Whakawehe 15-9x ki te -8.
