Kua tāruatia ki te papatopenga
2\left(x+2\right)=8
Tē taea kia ōrite te tāupe x ki -2 nā te kore tautuhi i te whakawehenga mā te kore. Whakareatia ngā taha e rua o te whārite ki te 2\left(x+2\right).
2x+4=8
Whakamahia te āhuatanga tohatoha hei whakarea te 2 ki te x+2.
2x=8-4
Tangohia te 4 mai i ngā taha e rua.
2x=4
Tangohia te 4 i te 8, ka 4.
x=\frac{4}{2}
Whakawehea ngā taha e rua ki te 2.
x=2
Whakawehea te 4 ki te 2, kia riro ko 2.
Ngā Tauira
whārite tapawhā
