Kua tāruatia ki te papatopenga
-27x-8=0
Pahekotia te 4x me -31x, ka -27x.
-27x=8
Me tāpiri te 8 ki ngā taha e rua. Ko te tau i tāpiria he kore ka hua koia tonu.
x=\frac{8}{-27}
Whakawehea ngā taha e rua ki te -27.
x=-\frac{8}{27}
Ka taea te hautanga \frac{8}{-27} te tuhi anō ko -\frac{8}{27} mā te tango i te tohu tōraro.
