Kua tāruatia ki te papatopenga
0\left(7x+14\right)=16-\left(x+2\right)
Whakareatia te 0 ki te 4, ka 0.
0=16-\left(x+2\right)
Ko te tau i whakarea ki te kore ka hua ko te kore.
0=16-x-2
Hei kimi i te tauaro o x+2, kimihia te tauaro o ia taurangi.
0=14-x
Tangohia te 2 i te 16, ka 14.
14-x=0
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
-x=-14
Tangohia te 14 mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
x=14
Me whakarea ngā taha e rua ki te -1.
