Tohaina
Kua tāruatia ki te papatopenga
-4y=-8-x
Tangohia te x mai i ngā taha e rua.
-4y=-x-8
He hanga arowhānui tō te whārite.
\frac{-4y}{-4}=\frac{-x-8}{-4}
Whakawehea ngā taha e rua ki te -4.
y=\frac{-x-8}{-4}
Mā te whakawehe ki te -4 ka wetekia te whakareanga ki te -4.
y=\frac{x}{4}+2
Whakawehe -8-x ki te -4.
x=-8+4y
Me tāpiri te 4y ki ngā taha e rua.
