Kua tāruatia ki te papatopenga
-10x=4-18y
Tangohia te 18y mai i ngā taha e rua.
\frac{-10x}{-10}=\frac{4-18y}{-10}
Whakawehea ngā taha e rua ki te -10.
x=\frac{4-18y}{-10}
Mā te whakawehe ki te -10 ka wetekia te whakareanga ki te -10.
x=\frac{9y-2}{5}
Whakawehe 4-18y ki te -10.
18y=4+10x
Me tāpiri te 10x ki ngā taha e rua.
18y=10x+4
He hanga arowhānui tō te whārite.
\frac{18y}{18}=\frac{10x+4}{18}
Whakawehea ngā taha e rua ki te 18.
y=\frac{10x+4}{18}
Mā te whakawehe ki te 18 ka wetekia te whakareanga ki te 18.
y=\frac{5x+2}{9}
Whakawehe 4+10x ki te 18.
