Kua tāruatia ki te papatopenga
2\left(1-x\right)=x-2
Whakaarohia te whārite tuatahi. Tē taea kia ōrite te tāupe x ki 2 nā te kore tautuhi i te whakawehenga mā te kore. Me whakarea ngā taha e rua o te whārite ki te 2\left(x-2\right), arā, te tauraro pātahi he tino iti rawa te kitea o x-2,2.
2-2x=x-2
Whakamahia te āhuatanga tohatoha hei whakarea te 2 ki te 1-x.
2-2x-x=-2
Tangohia te x mai i ngā taha e rua.
2-3x=-2
Pahekotia te -2x me -x, ka -3x.
-3x=-2-2
Tangohia te 2 mai i ngā taha e rua.
-3x=-4
Tangohia te 2 i te -2, ka -4.
x=\frac{-4}{-3}
Whakawehea ngā taha e rua ki te -3.
x=\frac{4}{3}
Ka taea te hautanga \frac{-4}{-3} te whakamāmā ki te \frac{4}{3} mā te tango tahi i te tohu tōraro i te taurunga me te tauraro.
x=\frac{4}{3} y=-2 z=-2 a=-2 b=-2
Kua oti te pūnaha te whakatau.
