Kua tāruatia ki te papatopenga
41x-2-50x=0
Tangohia te 50x mai i ngā taha e rua.
-9x-2=0
Pahekotia te 41x me -50x, ka -9x.
-9x=2
Me tāpiri te 2 ki ngā taha e rua. Ko te tau i tāpiria he kore ka hua koia tonu.
x=\frac{2}{-9}
Whakawehea ngā taha e rua ki te -9.
x=-\frac{2}{9}
Ka taea te hautanga \frac{2}{-9} te tuhi anō ko -\frac{2}{9} mā te tango i te tohu tōraro.
