4400+41x-54x=2450
Tangohia te 54x mai i ngā taha e rua.
4400-13x=2450
Pahekotia te 41x me -54x, ka -13x.
-13x=2450-4400
Tangohia te 4400 mai i ngā taha e rua.
-13x=-1950
Tangohia te 4400 i te 2450, ka -1950.
x=\frac{-1950}{-13}
Whakawehea ngā taha e rua ki te -13.
x=150
Whakawehea te -1950 ki te -13, kia riro ko 150.
