Kua tāruatia ki te papatopenga
\frac{4x}{9}-5-x=0
Tangohia te x mai i ngā taha e rua.
\frac{4x}{9}-x=5
Me tāpiri te 5 ki ngā taha e rua. Ko te tau i tāpiria he kore ka hua koia tonu.
4x-9x=45
Whakareatia ngā taha e rua o te whārite ki te 9.
-5x=45
Pahekotia te 4x me -9x, ka -5x.
x=\frac{45}{-5}
Whakawehea ngā taha e rua ki te -5.
x=-9
Whakawehea te 45 ki te -5, kia riro ko -9.
