Kua tāruatia ki te papatopenga
10-4d=-27\times \frac{2}{3}
Me whakarea ngā taha e rua ki te \frac{2}{3}, te tau utu o \frac{3}{2}.
10-4d=\frac{-27\times 2}{3}
Tuhia te -27\times \frac{2}{3} hei hautanga kotahi.
10-4d=\frac{-54}{3}
Whakareatia te -27 ki te 2, ka -54.
10-4d=-18
Whakawehea te -54 ki te 3, kia riro ko -18.
-4d=-18-10
Tangohia te 10 mai i ngā taha e rua.
-4d=-28
Tangohia te 10 i te -18, ka -28.
d=\frac{-28}{-4}
Whakawehea ngā taha e rua ki te -4.
d=7
Whakawehea te -28 ki te -4, kia riro ko 7.
