Kua tāruatia ki te papatopenga
2x=98+y
Me tāpiri te y ki ngā taha e rua.
2x=y+98
He hanga arowhānui tō te whārite.
\frac{2x}{2}=\frac{y+98}{2}
Whakawehea ngā taha e rua ki te 2.
x=\frac{y+98}{2}
Mā te whakawehe ki te 2 ka wetekia te whakareanga ki te 2.
x=\frac{y}{2}+49
Whakawehe 98+y ki te 2.
-y=98-2x
Tangohia te 2x mai i ngā taha e rua.
\frac{-y}{-1}=\frac{98-2x}{-1}
Whakawehea ngā taha e rua ki te -1.
y=\frac{98-2x}{-1}
Mā te whakawehe ki te -1 ka wetekia te whakareanga ki te -1.
y=2x-98
Whakawehe 98-2x ki te -1.
