Kua tāruatia ki te papatopenga
5x=17+2y
Me tāpiri te 2y ki ngā taha e rua.
5x=2y+17
He hanga arowhānui tō te whārite.
\frac{5x}{5}=\frac{2y+17}{5}
Whakawehea ngā taha e rua ki te 5.
x=\frac{2y+17}{5}
Mā te whakawehe ki te 5 ka wetekia te whakareanga ki te 5.
-2y=17-5x
Tangohia te 5x mai i ngā taha e rua.
\frac{-2y}{-2}=\frac{17-5x}{-2}
Whakawehea ngā taha e rua ki te -2.
y=\frac{17-5x}{-2}
Mā te whakawehe ki te -2 ka wetekia te whakareanga ki te -2.
y=\frac{5x-17}{2}
Whakawehe 17-5x ki te -2.
