Whakaoti mō d
d = -\frac{21}{8} = -2\frac{5}{8} = -2.625
Tohaina
Kua tāruatia ki te papatopenga
-8d-2=19
Tangohia te 4 i te 2, ka -2.
-8d=19+2
Me tāpiri te 2 ki ngā taha e rua.
-8d=21
Tāpirihia te 19 ki te 2, ka 21.
d=\frac{21}{-8}
Whakawehea ngā taha e rua ki te -8.
d=-\frac{21}{8}
Ka taea te hautanga \frac{21}{-8} te tuhi anō ko -\frac{21}{8} mā te tango i te tohu tōraro.
