30x+150-5x=550
Whakamahia te āhuatanga tohatoha hei whakarea te 30-x ki te 5.
25x+150=550
Pahekotia te 30x me -5x, ka 25x.
25x=550-150
Tangohia te 150 mai i ngā taha e rua.
25x=400
Tangohia te 150 i te 550, ka 400.
x=\frac{400}{25}
Whakawehea ngā taha e rua ki te 25.
x=16
Whakawehea te 400 ki te 25, kia riro ko 16.
