Whakaoti mō k
k = -\frac{9}{5} = -1\frac{4}{5} = -1.8
Tohaina
Kua tāruatia ki te papatopenga
10k=3\left(-6\right)
Me whakarea ngā taha e rua o te whārite ki te 30, arā, te tauraro pātahi he tino iti rawa te kitea o 3,10.
10k=-18
Whakareatia te 3 ki te -6, ka -18.
k=\frac{-18}{10}
Whakawehea ngā taha e rua ki te 10.
k=-\frac{9}{5}
Whakahekea te hautanga \frac{-18}{10} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.
