-2=-x-\left(-8\right)
Hei kimi i te tauaro o x-8, kimihia te tauaro o ia taurangi.
-2=-x+8
Ko te tauaro o -8 ko 8.
-x+8=-2
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
-x=-2-8
Tangohia te 8 mai i ngā taha e rua.
-x=-10
Tangohia te 8 i te -2, ka -10.
x=10
Me whakarea ngā taha e rua ki te -1.
