Whakaoti mō W
W = -\frac{14}{5} = -2\frac{4}{5} = -2.8
Tohaina
Kua tāruatia ki te papatopenga
14=\left(-W\right)\times 5
Tāpirihia te 4 ki te 10, ka 14.
\left(-W\right)\times 5=14
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
-W=\frac{14}{5}
Whakawehea ngā taha e rua ki te 5.
W=-\frac{14}{5}
Me whakarea ngā taha e rua ki te -1.
