Kua tāruatia ki te papatopenga
-\frac{9}{5}x=\frac{2}{5}-1
Tangohia te 1 mai i ngā taha e rua.
-\frac{9}{5}x=\frac{2}{5}-\frac{5}{5}
Me tahuri te 1 ki te hautau \frac{5}{5}.
-\frac{9}{5}x=\frac{2-5}{5}
Tā te mea he rite te tauraro o \frac{2}{5} me \frac{5}{5}, me tango rāua mā te tango i ō raua taurunga.
-\frac{9}{5}x=-\frac{3}{5}
Tangohia te 5 i te 2, ka -3.
x=-\frac{3}{5}\left(-\frac{5}{9}\right)
Me whakarea ngā taha e rua ki te -\frac{5}{9}, te tau utu o -\frac{9}{5}.
x=\frac{-3\left(-5\right)}{5\times 9}
Me whakarea te -\frac{3}{5} ki te -\frac{5}{9} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.
x=\frac{15}{45}
Mahia ngā whakarea i roto i te hautanga \frac{-3\left(-5\right)}{5\times 9}.
x=\frac{1}{3}
Whakahekea te hautanga \frac{15}{45} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 15.
