Kua tāruatia ki te papatopenga
-3x=2\left(x-14\right)
Tē taea kia ōrite te tāupe x ki 14 nā te kore tautuhi i te whakawehenga mā te kore. Me whakarea ngā taha e rua o te whārite ki te 3\left(x-14\right), arā, te tauraro pātahi he tino iti rawa te kitea o 14-x,3.
-3x=2x-28
Whakamahia te āhuatanga tohatoha hei whakarea te 2 ki te x-14.
-3x-2x=-28
Tangohia te 2x mai i ngā taha e rua.
-5x=-28
Pahekotia te -3x me -2x, ka -5x.
x=\frac{-28}{-5}
Whakawehea ngā taha e rua ki te -5.
x=\frac{28}{5}
Ka taea te hautanga \frac{-28}{-5} te whakamāmā ki te \frac{28}{5} mā te tango tahi i te tohu tōraro i te taurunga me te tauraro.
