18x+720-12x=16\times 60
Whakamahia te āhuatanga tohatoha hei whakarea te 12 ki te 60-x.
6x+720=16\times 60
Pahekotia te 18x me -12x, ka 6x.
6x+720=960
Whakareatia te 16 ki te 60, ka 960.
6x=960-720
Tangohia te 720 mai i ngā taha e rua.
6x=240
Tangohia te 720 i te 960, ka 240.
x=\frac{240}{6}
Whakawehea ngā taha e rua ki te 6.
x=40
Whakawehea te 240 ki te 6, kia riro ko 40.
