Kua tāruatia ki te papatopenga
x-\frac{9}{5}x=32
Tangohia te \frac{9}{5}x mai i ngā taha e rua.
-\frac{4}{5}x=32
Pahekotia te x me -\frac{9}{5}x, ka -\frac{4}{5}x.
x=32\left(-\frac{5}{4}\right)
Me whakarea ngā taha e rua ki te -\frac{5}{4}, te tau utu o -\frac{4}{5}.
x=\frac{32\left(-5\right)}{4}
Tuhia te 32\left(-\frac{5}{4}\right) hei hautanga kotahi.
x=\frac{-160}{4}
Whakareatia te 32 ki te -5, ka -160.
x=-40
Whakawehea te -160 ki te 4, kia riro ko -40.
