Kua tāruatia ki te papatopenga
180=6x-6+3x+2
Pahekotia te 4x me 2x, ka 6x.
180=9x-6+2
Pahekotia te 6x me 3x, ka 9x.
180=9x-4
Tāpirihia te -6 ki te 2, ka -4.
9x-4=180
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
9x=180+4
Me tāpiri te 4 ki ngā taha e rua.
9x=184
Tāpirihia te 180 ki te 4, ka 184.
x=\frac{184}{9}
Whakawehea ngā taha e rua ki te 9.
