Whakaoti mō v
v=-20
Tohaina
Kua tāruatia ki te papatopenga
v=15\left(-\frac{4}{3}\right)
Me whakarea ngā taha e rua ki te -\frac{4}{3}, te tau utu o -\frac{3}{4}.
v=\frac{15\left(-4\right)}{3}
Tuhia te 15\left(-\frac{4}{3}\right) hei hautanga kotahi.
v=\frac{-60}{3}
Whakareatia te 15 ki te -4, ka -60.
v=-20
Whakawehea te -60 ki te 3, kia riro ko -20.
