Kua tāruatia ki te papatopenga
9x=6+4y
Me tāpiri te 4y ki ngā taha e rua.
9x=4y+6
He hanga arowhānui tō te whārite.
\frac{9x}{9}=\frac{4y+6}{9}
Whakawehea ngā taha e rua ki te 9.
x=\frac{4y+6}{9}
Mā te whakawehe ki te 9 ka wetekia te whakareanga ki te 9.
x=\frac{4y}{9}+\frac{2}{3}
Whakawehe 6+4y ki te 9.
-4y=6-9x
Tangohia te 9x mai i ngā taha e rua.
\frac{-4y}{-4}=\frac{6-9x}{-4}
Whakawehea ngā taha e rua ki te -4.
y=\frac{6-9x}{-4}
Mā te whakawehe ki te -4 ka wetekia te whakareanga ki te -4.
y=\frac{9x}{4}-\frac{3}{2}
Whakawehe 6-9x ki te -4.
