Tohaina
Kua tāruatia ki te papatopenga
w-8=10w
Whakareatia ngā taha e rua o te whārite ki te -2.
w-8-10w=0
Tangohia te 10w mai i ngā taha e rua.
-9w-8=0
Pahekotia te w me -10w, ka -9w.
-9w=8
Me tāpiri te 8 ki ngā taha e rua. Ko te tau i tāpiria he kore ka hua koia tonu.
w=\frac{8}{-9}
Whakawehea ngā taha e rua ki te -9.
w=-\frac{8}{9}
Ka taea te hautanga \frac{8}{-9} te tuhi anō ko -\frac{8}{9} mā te tango i te tohu tōraro.
