Kua tāruatia ki te papatopenga
2x-1-6x=0
Tangohia te 6x mai i ngā taha e rua.
-4x-1=0
Pahekotia te 2x me -6x, ka -4x.
-4x=1
Me tāpiri te 1 ki ngā taha e rua. Ko te tau i tāpiria he kore ka hua koia tonu.
x=\frac{1}{-4}
Whakawehea ngā taha e rua ki te -4.
x=-\frac{1}{4}
Ka taea te hautanga \frac{1}{-4} te tuhi anō ko -\frac{1}{4} mā te tango i te tohu tōraro.
