Kua tāruatia ki te papatopenga
-4y=8-x
Tangohia te x mai i ngā taha e rua.
\frac{-4y}{-4}=\frac{8-x}{-4}
Whakawehea ngā taha e rua ki te -4.
y=\frac{8-x}{-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.
