Kua tāruatia ki te papatopenga
-1-7x=13
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
-7x=13+1
Me tāpiri te 1 ki ngā taha e rua.
-7x=14
Tāpirihia te 13 ki te 1, ka 14.
x=\frac{14}{-7}
Whakawehea ngā taha e rua ki te -7.
x=-2
Whakawehea te 14 ki te -7, kia riro ko -2.
