Kua tāruatia ki te papatopenga
x+96=12\left(x+2\right)\times 4
Whakaarohia te whārite tuatahi. Whakareatia ngā taha e rua o te whārite ki te 12.
x+96=48\left(x+2\right)
Whakareatia te 12 ki te 4, ka 48.
x+96=48x+96
Whakamahia te āhuatanga tohatoha hei whakarea te 48 ki te x+2.
x+96-48x=96
Tangohia te 48x mai i ngā taha e rua.
-47x+96=96
Pahekotia te x me -48x, ka -47x.
-47x=96-96
Tangohia te 96 mai i ngā taha e rua.
-47x=0
Tangohia te 96 i te 96, ka 0.
x=0
Whakawehea ngā taha e rua ki te -47. Ko te kore i whakawehea ki te tau ehara te kore ka hua ko te kore.
x=0 y=0 z=0
Kua oti te pūnaha te whakatau.
