Linear Equation
6.5 = - 0.5 x
Tohaina
Kua tāruatia ki te papatopenga
\frac{6.5}{-0.5}=x
Whakawehea ngā taha e rua ki te -0.5.
\frac{65}{-5}=x
Whakarohaina te \frac{6.5}{-0.5} mā te whakarea i te taurunga me te tauraro ki te 10.
-13=x
Whakawehea te 65 ki te -5, kia riro ko -13.
x=-13
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
