Linear Equation
5 raruraru e ōrite ana ki:
- 48 = \frac { \pi } { 2 } ( 2 ( 9 ) ( n - 1 ) - 2 )
Tohaina
Kua tāruatia ki te papatopenga
-96=\pi \left(2\times 9\left(n-1\right)-2\right)
Whakareatia ngā taha e rua o te whārite ki te 2.
-96=\pi \left(18\left(n-1\right)-2\right)
Whakareatia te 2 ki te 9, ka 18.
-96=\pi \left(18n-18-2\right)
Whakamahia te āhuatanga tohatoha hei whakarea te 18 ki te n-1.
-96=\pi \left(18n-20\right)
Tangohia te 2 i te -18, ka -20.
-96=18\pi n-20\pi
Whakamahia te āhuatanga tohatoha hei whakarea te \pi ki te 18n-20.
18\pi n-20\pi =-96
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
18\pi n=-96+20\pi
Me tāpiri te 20\pi ki ngā taha e rua.
18\pi n=20\pi -96
He hanga arowhānui tō te whārite.
\frac{18\pi n}{18\pi }=\frac{20\pi -96}{18\pi }
Whakawehea ngā taha e rua ki te 18\pi .
n=\frac{20\pi -96}{18\pi }
Mā te whakawehe ki te 18\pi ka wetekia te whakareanga ki te 18\pi .
n=-\frac{16}{3\pi }+\frac{10}{9}
Whakawehe -96+20\pi ki te 18\pi .
