7.2=\left(-x\right)\times \frac{1}{10000000000000000000}
Tātaihia te 10 mā te pū o -19, kia riro ko \frac{1}{10000000000000000000}.
\left(-x\right)\times \frac{1}{10000000000000000000}=7.2
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
-x=7.2\times 10000000000000000000
Me whakarea ngā taha e rua ki te 10000000000000000000, te tau utu o \frac{1}{10000000000000000000}.
-x=72000000000000000000
Whakareatia te 7.2 ki te 10000000000000000000, ka 72000000000000000000.
x=-72000000000000000000
Me whakarea ngā taha e rua ki te -1.
