Kua tāruatia ki te papatopenga
-\frac{2}{3}x=12
Pahekotia te \frac{1}{3}x me -x, ka -\frac{2}{3}x.
x=12\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{12\left(-3\right)}{2}
Tuhia te 12\left(-\frac{3}{2}\right) hei hautanga kotahi.
x=\frac{-36}{2}
Whakareatia te 12 ki te -3, ka -36.
x=-18
Whakawehea te -36 ki te 2, kia riro ko -18.
