Kua tāruatia ki te papatopenga
5x=8+3y
Me tāpiri te 3y ki ngā taha e rua.
5x=3y+8
He hanga arowhānui tō te whārite.
\frac{5x}{5}=\frac{3y+8}{5}
Whakawehea ngā taha e rua ki te 5.
x=\frac{3y+8}{5}
Mā te whakawehe ki te 5 ka wetekia te whakareanga ki te 5.
-3y=8-5x
Tangohia te 5x mai i ngā taha e rua.
\frac{-3y}{-3}=\frac{8-5x}{-3}
Whakawehea ngā taha e rua ki te -3.
y=\frac{8-5x}{-3}
Mā te whakawehe ki te -3 ka wetekia te whakareanga ki te -3.
y=\frac{5x-8}{3}
Whakawehe 8-5x ki te -3.
