Linear Equation
5 raruraru e ōrite ana ki:
\frac { 7 } { w } = \frac { 8 } { w } - \frac { 1 } { 5 }
Tohaina
Kua tāruatia ki te papatopenga
5\times 7=5\times 8+5w\left(-\frac{1}{5}\right)
Tē taea kia ōrite te tāupe w ki 0 nā te kore tautuhi i te whakawehenga mā te kore. Me whakarea ngā taha e rua o te whārite ki te 5w, arā, te tauraro pātahi he tino iti rawa te kitea o w,5.
35=5\times 8+5w\left(-\frac{1}{5}\right)
Whakareatia te 5 ki te 7, ka 35.
35=40+5w\left(-\frac{1}{5}\right)
Whakareatia te 5 ki te 8, ka 40.
35=40-w
Me whakakore te 5 me te 5.
40-w=35
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
-w=35-40
Tangohia te 40 mai i ngā taha e rua.
-w=-5
Tangohia te 40 i te 35, ka -5.
w=5
Me whakarea ngā taha e rua ki te -1.
