Kua tāruatia ki te papatopenga
5x=10+2y
Me tāpiri te 2y ki ngā taha e rua.
5x=2y+10
He hanga arowhānui tō te whārite.
\frac{5x}{5}=\frac{2y+10}{5}
Whakawehea ngā taha e rua ki te 5.
x=\frac{2y+10}{5}
Mā te whakawehe ki te 5 ka wetekia te whakareanga ki te 5.
x=\frac{2y}{5}+2
Whakawehe 10+2y ki te 5.
-2y=10-5x
Tangohia te 5x mai i ngā taha e rua.
\frac{-2y}{-2}=\frac{10-5x}{-2}
Whakawehea ngā taha e rua ki te -2.
y=\frac{10-5x}{-2}
Mā te whakawehe ki te -2 ka wetekia te whakareanga ki te -2.
y=\frac{5x}{2}-5
Whakawehe 10-5x ki te -2.
