Kua tāruatia ki te papatopenga
9x=10+3y
Me tāpiri te 3y ki ngā taha e rua.
9x=3y+10
He hanga arowhānui tō te whārite.
\frac{9x}{9}=\frac{3y+10}{9}
Whakawehea ngā taha e rua ki te 9.
x=\frac{3y+10}{9}
Mā te whakawehe ki te 9 ka wetekia te whakareanga ki te 9.
x=\frac{y}{3}+\frac{10}{9}
Whakawehe 10+3y ki te 9.
-3y=10-9x
Tangohia te 9x mai i ngā taha e rua.
\frac{-3y}{-3}=\frac{10-9x}{-3}
Whakawehea ngā taha e rua ki te -3.
y=\frac{10-9x}{-3}
Mā te whakawehe ki te -3 ka wetekia te whakareanga ki te -3.
y=3x-\frac{10}{3}
Whakawehe 10-9x ki te -3.
