\frac{2}{5}x+2-\frac{3}{2}x=-9
Tangohia te \frac{3}{2}x mai i ngā taha e rua.
-\frac{11}{10}x+2=-9
Pahekotia te \frac{2}{5}x me -\frac{3}{2}x, ka -\frac{11}{10}x.
-\frac{11}{10}x=-9-2
Tangohia te 2 mai i ngā taha e rua.
-\frac{11}{10}x=-11
Tangohia te 2 i te -9, ka -11.
x=-11\left(-\frac{10}{11}\right)
Me whakarea ngā taha e rua ki te -\frac{10}{11}, te tau utu o -\frac{11}{10}.
x=10
Whakareatia -11 ki te -\frac{10}{11}.
