Kua tāruatia ki te papatopenga
4\left(4x-3\right)=3\left(2x-5\right)
Tē taea kia ōrite te tāupe x ki \frac{5}{2} nā te kore tautuhi i te whakawehenga mā te kore. Me whakarea ngā taha e rua o te whārite ki te 4\left(2x-5\right), arā, te tauraro pātahi he tino iti rawa te kitea o 2x-5,4.
16x-12=3\left(2x-5\right)
Whakamahia te āhuatanga tohatoha hei whakarea te 4 ki te 4x-3.
16x-12=6x-15
Whakamahia te āhuatanga tohatoha hei whakarea te 3 ki te 2x-5.
16x-12-6x=-15
Tangohia te 6x mai i ngā taha e rua.
10x-12=-15
Pahekotia te 16x me -6x, ka 10x.
10x=-15+12
Me tāpiri te 12 ki ngā taha e rua.
10x=-3
Tāpirihia te -15 ki te 12, ka -3.
x=\frac{-3}{10}
Whakawehea ngā taha e rua ki te 10.
x=-\frac{3}{10}
Ka taea te hautanga \frac{-3}{10} te tuhi anō ko -\frac{3}{10} mā te tango i te tohu tōraro.
