Kua tāruatia ki te papatopenga
6x=-30+15y
Me tāpiri te 15y ki ngā taha e rua.
6x=15y-30
He hanga arowhānui tō te whārite.
\frac{6x}{6}=\frac{15y-30}{6}
Whakawehea ngā taha e rua ki te 6.
x=\frac{15y-30}{6}
Mā te whakawehe ki te 6 ka wetekia te whakareanga ki te 6.
x=\frac{5y}{2}-5
Whakawehe -30+15y ki te 6.
-15y=-30-6x
Tangohia te 6x mai i ngā taha e rua.
-15y=-6x-30
He hanga arowhānui tō te whārite.
\frac{-15y}{-15}=\frac{-6x-30}{-15}
Whakawehea ngā taha e rua ki te -15.
y=\frac{-6x-30}{-15}
Mā te whakawehe ki te -15 ka wetekia te whakareanga ki te -15.
y=\frac{2x}{5}+2
Whakawehe -30-6x ki te -15.
