Kua tāruatia ki te papatopenga
120x=100+120y
Me tāpiri te 120y ki ngā taha e rua.
120x=120y+100
He hanga arowhānui tō te whārite.
\frac{120x}{120}=\frac{120y+100}{120}
Whakawehea ngā taha e rua ki te 120.
x=\frac{120y+100}{120}
Mā te whakawehe ki te 120 ka wetekia te whakareanga ki te 120.
x=y+\frac{5}{6}
Whakawehe 100+120y ki te 120.
-120y=100-120x
Tangohia te 120x mai i ngā taha e rua.
\frac{-120y}{-120}=\frac{100-120x}{-120}
Whakawehea ngā taha e rua ki te -120.
y=\frac{100-120x}{-120}
Mā te whakawehe ki te -120 ka wetekia te whakareanga ki te -120.
y=x-\frac{5}{6}
Whakawehe 100-120x ki te -120.
