3\left(1\times 2+1\right)\left(x-\frac{2}{3}\right)=0
Whakaarohia te whārite tuatahi. Me whakarea ngā taha e rua o te whārite ki te 6, arā, te tauraro pātahi he tino iti rawa te kitea o 2,3.
3\left(2+1\right)\left(x-\frac{2}{3}\right)=0
Whakareatia te 1 ki te 2, ka 2.
3\times 3\left(x-\frac{2}{3}\right)=0
Tāpirihia te 2 ki te 1, ka 3.
9\left(x-\frac{2}{3}\right)=0
Whakareatia te 3 ki te 3, ka 9.
9x-6=0
Whakamahia te āhuatanga tohatoha hei whakarea te 9 ki te x-\frac{2}{3}.
9x=6
Me tāpiri te 6 ki ngā taha e rua. Ko te tau i tāpiria he kore ka hua koia tonu.
x=\frac{6}{9}
Whakawehea ngā taha e rua ki te 9.
x=\frac{2}{3}
Whakahekea te hautanga \frac{6}{9} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 3.
x=\frac{2}{3} y=2 z=2 a=2 b=2 c=2 d=2
Kua oti te pūnaha te whakatau.
