Linear Equation
5 raruraru e ōrite ana ki:
\frac { 7 } { w - 3 } = - \frac { 1 } { 4 w - 12 } + 2
Tohaina
Kua tāruatia ki te papatopenga
4\times 7=-1+4\left(w-3\right)\times 2
Tē taea kia ōrite te tāupe w ki 3 nā te kore tautuhi i te whakawehenga mā te kore. Me whakarea ngā taha e rua o te whārite ki te 4\left(w-3\right), arā, te tauraro pātahi he tino iti rawa te kitea o w-3,4w-12.
28=-1+4\left(w-3\right)\times 2
Whakareatia te 4 ki te 7, ka 28.
28=-1+8\left(w-3\right)
Whakareatia te 4 ki te 2, ka 8.
28=-1+8w-24
Whakamahia te āhuatanga tohatoha hei whakarea te 8 ki te w-3.
28=-25+8w
Tangohia te 24 i te -1, ka -25.
-25+8w=28
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
8w=28+25
Me tāpiri te 25 ki ngā taha e rua.
8w=53
Tāpirihia te 28 ki te 25, ka 53.
w=\frac{53}{8}
Whakawehea ngā taha e rua ki te 8.
