Kua tāruatia ki te papatopenga
x-9=3\left(-x+89\right)
Tē taea kia ōrite te tāupe x ki 89 nā te kore tautuhi i te whakawehenga mā te kore. Whakareatia ngā taha e rua o te whārite ki te -x+89.
x-9=-3x+267
Whakamahia te āhuatanga tohatoha hei whakarea te 3 ki te -x+89.
x-9+3x=267
Me tāpiri te 3x ki ngā taha e rua.
4x-9=267
Pahekotia te x me 3x, ka 4x.
4x=267+9
Me tāpiri te 9 ki ngā taha e rua.
4x=276
Tāpirihia te 267 ki te 9, ka 276.
x=\frac{276}{4}
Whakawehea ngā taha e rua ki te 4.
x=69
Whakawehea te 276 ki te 4, kia riro ko 69.
