Kua tāruatia ki te papatopenga
4x=8+y
Me tāpiri te y ki ngā taha e rua.
4x=y+8
He hanga arowhānui tō te whārite.
\frac{4x}{4}=\frac{y+8}{4}
Whakawehea ngā taha e rua ki te 4.
x=\frac{y+8}{4}
Mā te whakawehe ki te 4 ka wetekia te whakareanga ki te 4.
x=\frac{y}{4}+2
Whakawehe 8+y ki te 4.
-y=8-4x
Tangohia te 4x mai i ngā taha e rua.
\frac{-y}{-1}=\frac{8-4x}{-1}
Whakawehea ngā taha e rua ki te -1.
y=\frac{8-4x}{-1}
Mā te whakawehe ki te -1 ka wetekia te whakareanga ki te -1.
y=4x-8
Whakawehe 8-4x ki te -1.
