Kua tāruatia ki te papatopenga
-2\left(x-2\right)=3\left(x-3\right)
Tē taea kia ōrite te tāupe x ki 3 nā te kore tautuhi i te whakawehenga mā te kore. Me whakarea ngā taha e rua o te whārite ki te 2\left(x-3\right), arā, te tauraro pātahi he tino iti rawa te kitea o 3-x,2.
-2x+4=3\left(x-3\right)
Whakamahia te āhuatanga tohatoha hei whakarea te -2 ki te x-2.
-2x+4=3x-9
Whakamahia te āhuatanga tohatoha hei whakarea te 3 ki te x-3.
-2x+4-3x=-9
Tangohia te 3x mai i ngā taha e rua.
-5x+4=-9
Pahekotia te -2x me -3x, ka -5x.
-5x=-9-4
Tangohia te 4 mai i ngā taha e rua.
-5x=-13
Tangohia te 4 i te -9, ka -13.
x=\frac{-13}{-5}
Whakawehea ngā taha e rua ki te -5.
x=\frac{13}{5}
Ka taea te hautanga \frac{-13}{-5} te whakamāmā ki te \frac{13}{5} mā te tango tahi i te tohu tōraro i te taurunga me te tauraro.
