Tohaina
Kua tāruatia ki te papatopenga
12+3b=0
Whakaarohia te whārite tuatahi. Tē taea kia ōrite te tāupe a ki -9 nā te kore tautuhi i te whakawehenga mā te kore. Whakareatia ngā taha e rua o te whārite ki te 2\left(a+9\right).
3b=-12
Tangohia te 12 mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
b=\frac{-12}{3}
Whakawehea ngā taha e rua ki te 3.
b=-4
Whakawehea te -12 ki te 3, kia riro ko -4.
b=-4 c=6 d=6
Kua oti te pūnaha te whakatau.
