Tohaina
Kua tāruatia ki te papatopenga
4x+1=-x_{2}
Tangohia te x_{2} mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
4x=-x_{2}-1
Tangohia te 1 mai i ngā taha e rua.
\frac{4x}{4}=\frac{-x_{2}-1}{4}
Whakawehea ngā taha e rua ki te 4.
x=\frac{-x_{2}-1}{4}
Mā te whakawehe ki te 4 ka wetekia te whakareanga ki te 4.
x_{2}+1=-4x
Tangohia te 4x mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
x_{2}=-4x-1
Tangohia te 1 mai i ngā taha e rua.
