Kua tāruatia ki te papatopenga
\frac{1}{3}x-\frac{2}{3}=x
Whakawehea ia wā o x-2 ki te 3, kia riro ko \frac{1}{3}x-\frac{2}{3}.
\frac{1}{3}x-\frac{2}{3}-x=0
Tangohia te x mai i ngā taha e rua.
-\frac{2}{3}x-\frac{2}{3}=0
Pahekotia te \frac{1}{3}x me -x, ka -\frac{2}{3}x.
-\frac{2}{3}x=\frac{2}{3}
Me tāpiri te \frac{2}{3} ki ngā taha e rua. Ko te tau i tāpiria he kore ka hua koia tonu.
x=\frac{2}{3}\left(-\frac{3}{2}\right)
Me whakarea ngā taha e rua ki te -\frac{3}{2}, te tau utu o -\frac{2}{3}.
x=\frac{2\left(-3\right)}{3\times 2}
Me whakarea te \frac{2}{3} ki te -\frac{3}{2} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.
x=\frac{-3}{3}
Me whakakore tahi te 2 i te taurunga me te tauraro.
x=-1
Whakawehea te -3 ki te 3, kia riro ko -1.
