Kua tāruatia ki te papatopenga
10\left(3x+2\right)=2x-3
Tē taea kia ōrite te tāupe x ki -\frac{2}{3} nā te kore tautuhi i te whakawehenga mā te kore. Whakareatia ngā taha e rua o te whārite ki te 3x+2.
30x+20=2x-3
Whakamahia te āhuatanga tohatoha hei whakarea te 10 ki te 3x+2.
30x+20-2x=-3
Tangohia te 2x mai i ngā taha e rua.
28x+20=-3
Pahekotia te 30x me -2x, ka 28x.
28x=-3-20
Tangohia te 20 mai i ngā taha e rua.
28x=-23
Tangohia te 20 i te -3, ka -23.
x=\frac{-23}{28}
Whakawehea ngā taha e rua ki te 28.
x=-\frac{23}{28}
Ka taea te hautanga \frac{-23}{28} te tuhi anō ko -\frac{23}{28} mā te tango i te tohu tōraro.
