Kua tāruatia ki te papatopenga
9x=-18+3y
Me tāpiri te 3y ki ngā taha e rua.
9x=3y-18
He hanga arowhānui tō te whārite.
\frac{9x}{9}=\frac{3y-18}{9}
Whakawehea ngā taha e rua ki te 9.
x=\frac{3y-18}{9}
Mā te whakawehe ki te 9 ka wetekia te whakareanga ki te 9.
x=\frac{y}{3}-2
Whakawehe -18+3y ki te 9.
-3y=-18-9x
Tangohia te 9x mai i ngā taha e rua.
-3y=-9x-18
He hanga arowhānui tō te whārite.
\frac{-3y}{-3}=\frac{-9x-18}{-3}
Whakawehea ngā taha e rua ki te -3.
y=\frac{-9x-18}{-3}
Mā te whakawehe ki te -3 ka wetekia te whakareanga ki te -3.
y=3x+6
Whakawehe -18-9x ki te -3.
