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