Kua tāruatia ki te papatopenga
9x=-22-3y
Tangohia te 3y mai i ngā taha e rua.
9x=-3y-22
He hanga arowhānui tō te whārite.
\frac{9x}{9}=\frac{-3y-22}{9}
Whakawehea ngā taha e rua ki te 9.
x=\frac{-3y-22}{9}
Mā te whakawehe ki te 9 ka wetekia te whakareanga ki te 9.
x=-\frac{y}{3}-\frac{22}{9}
Whakawehe -22-3y ki te 9.
3y=-22-9x
Tangohia te 9x mai i ngā taha e rua.
3y=-9x-22
He hanga arowhānui tō te whārite.
\frac{3y}{3}=\frac{-9x-22}{3}
Whakawehea ngā taha e rua ki te 3.
y=\frac{-9x-22}{3}
Mā te whakawehe ki te 3 ka wetekia te whakareanga ki te 3.
y=-3x-\frac{22}{3}
Whakawehe -22-9x ki te 3.
