Kua tāruatia ki te papatopenga
-4x=-15-3y
Tangohia te 3y mai i ngā taha e rua.
-4x=-3y-15
He hanga arowhānui tō te whārite.
\frac{-4x}{-4}=\frac{-3y-15}{-4}
Whakawehea ngā taha e rua ki te -4.
x=\frac{-3y-15}{-4}
Mā te whakawehe ki te -4 ka wetekia te whakareanga ki te -4.
x=\frac{3y+15}{4}
Whakawehe -15-3y ki te -4.
3y=-15+4x
Me tāpiri te 4x ki ngā taha e rua.
3y=4x-15
He hanga arowhānui tō te whārite.
\frac{3y}{3}=\frac{4x-15}{3}
Whakawehea ngā taha e rua ki te 3.
y=\frac{4x-15}{3}
Mā te whakawehe ki te 3 ka wetekia te whakareanga ki te 3.
y=\frac{4x}{3}-5
Whakawehe -15+4x ki te 3.
