Kua tāruatia ki te papatopenga
\frac{2}{5}x-7-\frac{6}{5}x=-6
Tangohia te \frac{6}{5}x mai i ngā taha e rua.
-\frac{4}{5}x-7=-6
Pahekotia te \frac{2}{5}x me -\frac{6}{5}x, ka -\frac{4}{5}x.
-\frac{4}{5}x=-6+7
Me tāpiri te 7 ki ngā taha e rua.
-\frac{4}{5}x=1
Tāpirihia te -6 ki te 7, ka 1.
x=1\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{5}{4}
Whakareatia te 1 ki te -\frac{5}{4}, ka -\frac{5}{4}.
