Kua tāruatia ki te papatopenga
6x+13-x=0
Tangohia te x mai i ngā taha e rua.
5x+13=0
Pahekotia te 6x me -x, ka 5x.
5x=-13
Tangohia te 13 mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
x=\frac{-13}{5}
Whakawehea ngā taha e rua ki te 5.
x=-\frac{13}{5}
Ka taea te hautanga \frac{-13}{5} te tuhi anō ko -\frac{13}{5} mā te tango i te tohu tōraro.
