Tohaina
Kua tāruatia ki te papatopenga
-8=\frac{-b}{-34}
Whakareatia te 2 ki te -17, ka -34.
\frac{-b}{-34}=-8
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
-b=-8\left(-34\right)
Me whakarea ngā taha e rua ki te -34.
-b=272
Whakareatia te -8 ki te -34, ka 272.
b=-272
Me whakarea ngā taha e rua ki te -1.
