x+1206-81x=166
Whakamahia te āhuatanga tohatoha hei whakarea te 9 ki te 134-9x.
-80x+1206=166
Pahekotia te x me -81x, ka -80x.
-80x=166-1206
Tangohia te 1206 mai i ngā taha e rua.
-80x=-1040
Tangohia te 1206 i te 166, ka -1040.
x=\frac{-1040}{-80}
Whakawehea ngā taha e rua ki te -80.
x=13
Whakawehea te -1040 ki te -80, kia riro ko 13.
