\frac{2}{3}x-\frac{1}{9}x-\frac{1}{9}x=-1-1
Pahekotia te x me -\frac{1}{3}x, ka \frac{2}{3}x.
\frac{5}{9}x-\frac{1}{9}x=-1-1
Pahekotia te \frac{2}{3}x me -\frac{1}{9}x, ka \frac{5}{9}x.
\frac{4}{9}x=-1-1
Pahekotia te \frac{5}{9}x me -\frac{1}{9}x, ka \frac{4}{9}x.
\frac{4}{9}x=-2
Tangohia te 1 i te -1, ka -2.
x=-2\times \frac{9}{4}
Me whakarea ngā taha e rua ki te \frac{9}{4}, te tau utu o \frac{4}{9}.
x=\frac{-2\times 9}{4}
Tuhia te -2\times \frac{9}{4} hei hautanga kotahi.
x=\frac{-18}{4}
Whakareatia te -2 ki te 9, ka -18.
x=-\frac{9}{2}
Whakahekea te hautanga \frac{-18}{4} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.
