Kua tāruatia ki te papatopenga
6x+4x+3x=156
Me whakarea ngā taha e rua o te whārite ki te 12, arā, te tauraro pātahi he tino iti rawa te kitea o 2,3,4.
10x+3x=156
Pahekotia te 6x me 4x, ka 10x.
13x=156
Pahekotia te 10x me 3x, ka 13x.
x=\frac{156}{13}
Whakawehea ngā taha e rua ki te 13.
x=12
Whakawehea te 156 ki te 13, kia riro ko 12.
