Whakaoti mō x_1
x_{1}=x_{2}+25
Whakaoti mō x_2
x_{2}=x_{1}-25
Tohaina
Kua tāruatia ki te papatopenga
x_{1}-25=x_{2}
Me tāpiri te x_{2} ki ngā taha e rua. Ko te tau i tāpiria he kore ka hua koia tonu.
x_{1}=x_{2}+25
Me tāpiri te 25 ki ngā taha e rua.
-x_{2}-25=-x_{1}
Tangohia te x_{1} mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
-x_{2}=-x_{1}+25
Me tāpiri te 25 ki ngā taha e rua.
-x_{2}=25-x_{1}
He hanga arowhānui tō te whārite.
\frac{-x_{2}}{-1}=\frac{25-x_{1}}{-1}
Whakawehea ngā taha e rua ki te -1.
x_{2}=\frac{25-x_{1}}{-1}
Mā te whakawehe ki te -1 ka wetekia te whakareanga ki te -1.
x_{2}=x_{1}-25
Whakawehe -x_{1}+25 ki te -1.
