Tohaina
Kua tāruatia ki te papatopenga
3x=-3x+6\left(2x+7\right)
Tē taea kia ōrite te tāupe x ki -1 nā te kore tautuhi i te whakawehenga mā te kore. Me whakarea ngā taha e rua o te whārite ki te 6\left(x+1\right), arā, te tauraro pātahi he tino iti rawa te kitea o 2x+2,6x+6,x+1.
3x=-3x+12x+42
Whakamahia te āhuatanga tohatoha hei whakarea te 6 ki te 2x+7.
3x=9x+42
Pahekotia te -3x me 12x, ka 9x.
3x-9x=42
Tangohia te 9x mai i ngā taha e rua.
-6x=42
Pahekotia te 3x me -9x, ka -6x.
x=\frac{42}{-6}
Whakawehea ngā taha e rua ki te -6.
x=-7
Whakawehea te 42 ki te -6, kia riro ko -7.
