Kua tāruatia ki te papatopenga
7\left(3X-2\right)=4\left(2X-3\right)
Tē taea kia ōrite te tāupe X ki \frac{3}{2} nā te kore tautuhi i te whakawehenga mā te kore. Me whakarea ngā taha e rua o te whārite ki te 7\left(2X-3\right), arā, te tauraro pātahi he tino iti rawa te kitea o 2X-3,7.
21X-14=4\left(2X-3\right)
Whakamahia te āhuatanga tohatoha hei whakarea te 7 ki te 3X-2.
21X-14=8X-12
Whakamahia te āhuatanga tohatoha hei whakarea te 4 ki te 2X-3.
21X-14-8X=-12
Tangohia te 8X mai i ngā taha e rua.
13X-14=-12
Pahekotia te 21X me -8X, ka 13X.
13X=-12+14
Me tāpiri te 14 ki ngā taha e rua.
13X=2
Tāpirihia te -12 ki te 14, ka 2.
X=\frac{2}{13}
Whakawehea ngā taha e rua ki te 13.
