Tohaina
Kua tāruatia ki te papatopenga
2a+2c=-2b
Tangohia te 2b mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
2a=-2b-2c
Tangohia te 2c mai i ngā taha e rua.
\frac{2a}{2}=\frac{-2b-2c}{2}
Whakawehea ngā taha e rua ki te 2.
a=\frac{-2b-2c}{2}
Mā te whakawehe ki te 2 ka wetekia te whakareanga ki te 2.
a=-b-c
Whakawehe -2b-2c ki te 2.
2b+2c=-2a
Tangohia te 2a mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
2b=-2a-2c
Tangohia te 2c mai i ngā taha e rua.
\frac{2b}{2}=\frac{-2a-2c}{2}
Whakawehea ngā taha e rua ki te 2.
b=\frac{-2a-2c}{2}
Mā te whakawehe ki te 2 ka wetekia te whakareanga ki te 2.
b=-a-c
Whakawehe -2a-2c ki te 2.
