Tohaina
Kua tāruatia ki te papatopenga
10x+6y+360-6x-6y=680
Whakamahia te āhuatanga tohatoha hei whakarea te 6 ki te 60-x-y.
4x+6y+360-6y=680
Pahekotia te 10x me -6x, ka 4x.
4x+360=680
Pahekotia te 6y me -6y, ka 0.
4x=680-360
Tangohia te 360 mai i ngā taha e rua.
4x=320
Tangohia te 360 i te 680, ka 320.
x=\frac{320}{4}
Whakawehea ngā taha e rua ki te 4.
x=80
Whakawehea te 320 ki te 4, kia riro ko 80.
