Kua tāruatia ki te papatopenga
-2x=1-3y
Tangohia te 3y mai i ngā taha e rua.
\frac{-2x}{-2}=\frac{1-3y}{-2}
Whakawehea ngā taha e rua ki te -2.
x=\frac{1-3y}{-2}
Mā te whakawehe ki te -2 ka wetekia te whakareanga ki te -2.
x=\frac{3y-1}{2}
Whakawehe 1-3y ki te -2.
3y=1+2x
Me tāpiri te 2x ki ngā taha e rua.
3y=2x+1
He hanga arowhānui tō te whārite.
\frac{3y}{3}=\frac{2x+1}{3}
Whakawehea ngā taha e rua ki te 3.
y=\frac{2x+1}{3}
Mā te whakawehe ki te 3 ka wetekia te whakareanga ki te 3.
