Tohaina
Kua tāruatia ki te papatopenga
x=140-x_{0}\times 4
Tangohia te x_{0}\times 4 mai i ngā taha e rua.
x=140-4x_{0}
Whakareatia te -1 ki te 4, ka -4.
x_{0}\times 4=140-x
Tangohia te x mai i ngā taha e rua.
4x_{0}=140-x
He hanga arowhānui tō te whārite.
\frac{4x_{0}}{4}=\frac{140-x}{4}
Whakawehea ngā taha e rua ki te 4.
x_{0}=\frac{140-x}{4}
Mā te whakawehe ki te 4 ka wetekia te whakareanga ki te 4.
x_{0}=-\frac{x}{4}+35
Whakawehe 140-x ki te 4.
