Kua tāruatia ki te papatopenga
15x-27-2\times 6=0
Whakamahia te āhuatanga tohatoha hei whakarea te 3 ki te 5x-9.
15x-27-12=0
Whakareatia te 2 ki te 6, ka 12.
15x-39=0
Tangohia te 12 i te -27, ka -39.
15x=39
Me tāpiri te 39 ki ngā taha e rua. Ko te tau i tāpiria he kore ka hua koia tonu.
x=\frac{39}{15}
Whakawehea ngā taha e rua ki te 15.
x=\frac{13}{5}
Whakahekea te hautanga \frac{39}{15} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 3.
